I think my best friend is pulling away.
So a bit of context, me (27M) and my friend (30M) have been best friends for over 7 years now. We met right before covid playing games online and ever since then have been inseparable. We talk about everything, from major deaths in the family to what the new One-Piece theories are, I honestly don't think we have gone longer than a couple of days between at least texting since early 2020. We talk about moving closer together so that one day our kids can grow up together one day.
So last year he met the love of his life, and I think she is amazing for him and has made him so happy. They just got married this year and I was the best man where everything was wonderful. I stayed at their place, and I would like to think me and the wife have a friendly relationship. Ever since the wedding though, things seem to have changed.
It started with simple things, him not having time for late night weekend gaming sessions due to wanting to spend it with his wife. Less calls talking about sports and stupid shit we had experienced over the week. I kind of just chalked it up to being busy with/enjoying his married life. I should preface this before I continue this story, my childhood best friend that I knew from 7-21 ruined our last friendship and isolated me right after he got married as well. Same situation, best man, brothers, talked about everything and had a good relationship with his spouse. So, I have some trauma from this and am kind of panicking a bit.
Recently I have noticed though that it's not just that, but all the little things that made us feel like brothers seem to have just, stopped. I'll message him about the wild basketball game, and two days later he will respond with a short one-word answer and not respond to the follow up I send. I know that he has been busy at work, but I know this cause his wife sent me a meme like a week ago and it got brought up. in response to this I sent him a message saying hope he's doing well and if he wants to relax and destress like how we usually do just to give me a call. A week later he responded saying he was sorry for the long silence, but work has been crazy. Said him and his wife we are taking a last-minute minivacation to relax, and he wouldn't be able to talk this weekend. I understood and asked where they were going, and have not received a response since.
I think what has kind of hurt the most is we had a plan before his wedding that I would come up to see him and his wife for my birthday and enjoy it together, his idea. My birthday is next week and ever since this started happening, I haven't heard one word about it and am worried he has forgotten.
I know that when you get married that 99% of your focus and energy go towards your partner, but is it valid to be a bit hurt/worried about what this means long term for our friendship?
