I (F19) have been with my bf (M19) for almost three years. We go to the same university, we both love video games, we get along amazing with each other’s friends. It’s all going great as of late. Today while we were out at lunch, I saw him get a notification that a name I didn’t recognize had added him back on snapchat, so I asked him who that was. He immediately turned to this joking thing he does where he changes his voice and acts like I’m overreacting. It’s something his friends do to each other so I’m used to it and wasn’t offended. I let it go, but a few minutes later he got another notification from snapchat saying someone had added him. He gave the same response when I asked him about it, but this time I told him it wasn’t funny. He told me “it’s fine that was from a couple months ago.” Now correct me if I’m wrong but “a couple months”<almost three years. He should not have been adding random ass girls on snapchat a couple months ago. I tried to let it slide through the day. Later on in the evening (after I had unsuccessfully gotten over it and ended up SHing because that just made me feel like I’m not enough for him), I saw him get a notification from yet another girl on Snapchat. Again I asked, “Who is that?” This time his response was to get frustrated and he looked like he was about to cry. He kept saying over and over while hugging me “I don’t know they just add me I don’t know them I don’t know them” We were in public so I tried to really tone down the situation and forget it. But, it does make me uncomfortable. I know he wouldn’t cheat on me. He’s autistic and has been with me for a long time, especially for teenagers. He has never shown signs of interest in anyone else or in breaking up. And I must admit, I do get really insecure when it comes to other women. That’s not a concern that I developed through his actions, it’s definitely from childhood or something. I feel like I need to talk to him about it because we’ve had this conversation once before, 2ish years ago. I just don’t understand why he thinks he needs to add/add back random ass people, especially when he is in a committed relationship. But I also feel like that’s just how some people use social media. AITAH for wanting him to stop adding random girls?
