I traveled to my girlfriend's house for my birthday and I must admit it hasn't been easy. I've been insecure for a few months and I told her about it, and she thought it was nonsense, that I was being controlling etc
At her house, I went into her Discord and saw that she was exchanging some rather uncomfortable messages with a guy she played Fortnite with. It wasn't anything THAT explicit, but they were the kind of messages where the person is clearly flirting with you, but you don't cut them off, you know? The message that upset me the most was her talking about selling photos of her feet to buy a game, and him replying "I would buy it." That really upset me. I told her and we argued a lot over the days, she completely cut off contact with the guy and told me that from now on she will respect our relationship more. And I agreed and tried to move on.
However, something still bothered me, so I went to the apps she had already downloaded on her phone and found out: she had used Bumble while we were still dating. There are no emails on her phone proving she was actually using it or that she created an account, since many of her old emails were deleted, but the app was STILL there. It had been downloaded.
I just confronted her, and her only argument was that she doesn't remember using it, doesn't remember talking to someone or creating an account, because it had been so long that she didn't even remember. To be honest, I'm really annoyed because it's a completely meaningless answer; it doesn't actually give me a real solution. I feel like I'm overreacting, but at the same time, I know I'm not. She said, "It's in your hands, since you're looking for things and it's not doing you any good, end the relationship."
I really don't know what to do. I know it's in my hands and I know that, obviously, I should end it. But I just wanted a reason why she downloaded it, and she didn't even explain it to me.
