My girlfriend (22) and I (25) have been together 3 years, living together for 1.5, she has many friends online being that we live in a very rural area with not much to do. Many of those friends are guys which doesn’t bother me for the most part I’m friends with them as well but, there was a guy friend maybe 2 months back she had that was treating her not the best and she came to me crying about it on multiple occasions, which already made me feel off just her crying over a guy multiple times was something I hadn’t experienced in any other relationship, I told her what I thought and told her to protect her peace and cut communication. I thought that was the end of it, she seemed better overall without him around. Maybe 3 days ago I walked in her office to her crying again, he messaged her on discord to see how she was (she is nowhere near forgiving him) , it kinda upset me that she had left the door open for that and also that she was crying over this man for maybe a 5th time at this point…Reddit AITAH for feeling upset over this?
