AIO- having a friend not join our D&D group Am I overreacting in this situation
So there are 4 people involved in this story, me, and my 3 friends who I am going to call Tori, Cindy and Baker (not real names) (all f 26/27).
When I was younger I moved schools a lot as we moved house several times due to my parents' jobs. At the first school I went to I made friends with a girl named Cindy a few months later I moved and changed schools again and became friends with two girls (well four though two are irrelevant to the story) named Tori and Baker. I didn’t see Cindy much but we hadn't moved too far so when I had birthday parties or slumber parties I would invite Cindy to join and so she met Tori and Baker. As time went on her and Baker got along really well and the two of them became best friends. We were still a group of friends but there was a clear divide between the two of them and me and Tori, they would often meet up without us which honestly didn't bother me at the time but I know did bother Tori a little.
When we went to high school Baker, Cindy and I all got into the same school while Tori went to another one. We were sad not to see her every day but we still invited her when we hung out outside of school.
At high school we met another girl (let's call her Mary) and the four of us became friends. Tori knew her as they had previously lived in the same town. Throughout high school me, Baker and Cindy would often fight as Mary tried to pit us against each other and would tell Cindy and Baker that me and Tori had said and done things we hadn't leading to Cindy forcing the others to exclude me.
Mary was genuinely insane to summarise her most ridiculous actions: she convinced Tori to fake having a boyfriend to prank us all, outed both me and Tori to our parents, briefly dated Baker and then broke up with her three days later because she decided she didn't actually like her because the fish Baker had won her at the carnival died, told Tori that she should stop being so dramatic for being worried that her cousin lived in the path of Hurricane Irma "as people die every day", would regularly try and make me pay for her lunch at school (her parents were loaded and gave her money so idk why she did this), read Stucky smut outloud on the bus to school and moaned very loudly while doing it, claimed that her dad was a dangerous alcoholic that CPS were investigating (we have it on good authority that this was a complete lie).
I didn't know that Mary had been lying to Baker and Cindy until very recently (about two months ago during a conversation with Baker and Tori when Tori literally showed me text receipts) from my perspective I just thought Cindy and Baker hated me but apparently Mary had been lying to them. At the time my family life had been super complicated and I had started to get quite seriously ill and so I hadn't really thought much about it I just thought my friends hated me and ended up meeting other people through classes that I got closer too.
To make a long story short we stopped talking to Mary after she did something truly heinous that I will not go into the details of and none of us have seen her in a good 10 years at this point. Me, Baker and Cindy made up as much as we could and just kind of ignored everything that had happened with Mary. I got closer to my other friends who I had made in high school and though we saw each other still, things were never really the same between me, Tori, Baker and Cindy.
When we all graduated high school I stayed in our hometown and so did Baker and Tori but Cindy moved a little ways away to go to college. We would still see each other some times at holidays but not much as we all got busy with adult life. Due to some health related things on both our parts me and Tori lost touch shortly after high school as neither of us were very able to leave our houses without help (and having to have your parents sit with you in a coffee shop so you can see your friend as an adult is lowkey awkward lol). Cindy and Baker also stopped messaging Tori when she got ill though I'm not entirely sure why. None of them have said anything bad happened but to be fair to them of them, Baker and Cindy didn't tend to meet up with Tori unless I was around especially after our fall out with Mary, unlike me. Gradually we all drifted away from each other but occasionally Cindy or Baker would message me and I would see one of them for coffee though it got less and less frequent and more complicated as the pandemic hit and I got more unwell. Baker and Cindy stayed friends though and were still closer than the rest of us.
A few years ago Cindy went travelling. She said she would be gone 6 months but that kept getting extended. When she left she pretty much stopped messaging any of us.
While she was away my health started to get a bit better and I got back in touch with Tori on a whim and we got really close. We pretty much talk everyday now and are really good friends. I also started to see Baker more often as I was able to get out on my own finally!
One day Tori messaged me and asked if I would be interested in setting up a dnd group with her as she knew I ran another one online. I said of course and asked if she knew anyone here in our hometown who would be interested in joining. She said she didn't so I messaged Baker along with a friend who I met online a little while ago after high school who had moved close by and they both said yes. We started our group and since we did we have both been talking to/meeting up with Baker a lot more often. We all still get on great and Baker is a lovely person.
A few days ago Baker got a message from Cindy saying she was back and asking for help getting a job. No "how are you?" no "do you wanna meet up?" just "can you get me a job where you work?" Baker told me and Tori when we bumped into her the other day at the grocery store and we both thought it was a little odd as she hasn't contacted any of us in several years now and none of us even knew she had come back. It also seemed odd she didn't seem interested in at least being pleasant to Baker who was her closest friend of all of us.
Yesterday I sent a message to the group chat we have for dnd to ask about planning the next session and Baker replied asking if we should invite Cindy to join our party seeing as she's back. I wouldn't mind it too much but I know that it would make Tori uncomfortable as Cindy was pretty shitty to her at some points (and me too tbh but I just can't be bothered to hold a grudge) and she pretty much ghosted both of us when things got complicated. Dnd can be something that requires a certain level of trust and pre-existing relationships and so I don't know if that would be complicated as all of us have a complicated history with Cindy and we haven't talked in literal years. I also genuinely don't know if Cindy would be into dnd or if she has played before and we are in the middle of a campaign so idk if it would make sense to have her join right now from a practical point of view. She has also never been "nerdy" in the same way that me, Tori and Baker have she was always more popular and into sports (etc.) while the three of us were band kids who were into sci-fi and video games. Part of me feels that if I ask she might feel obligated to join and then it might make things awkward as she doesn't actually want to be there and she feels odd being back in a dynamic that is now over ten years old and then our dnd group might slowly die as everyone feels awkward. On the other hand it might go great I just don't think that it's super likely to and I don't want to end up losing Baker and Tori as we all fall into stupid high school roles from a literal decade ago. There is also our fourth party member to consider as they have never met Cindy and don't know the full story of the complicated past that the rest of us have had as me, Baker and Tori agreed to just forget everything.
I genuinely don't know if I'm just being petty or overthinking this because to be honest I feel a little bit like I am acting like a high schooler again rn but would I be the asshole if I said no to Cindy joining our party?
