I (21F) and my now boyfriend (28M) have been together for almost a year. Today I got upset because he is watching a YouTube video that my ex best friend watches to I’m not just upset over him watching a YouTube video I’m upset over him watching a YouTube video when the girl he cheated (sent nude) on me who watch’s the same YouTuber.

He was watching the YouTuber (MrBallen) before he met me and after he cheated on me we decided to work it out and we are engaged now.

I told him that I wasn’t going to watch it and I have told him how I feel more then once but he keeps telling me I’m trying to take it away from him because my ex best friend watch’s it.

He told me that when the person is live or in the state we live at he wanted to go see them I told him I don’t want to go he will just go alone but instead he said he will just take someone else since I didn’t want to go and I got more upset because I don’t think that he understand that if my ex best friend likes the YouTuber that she will probably be there to.

During the fight he kept just saying that me and her probably have stuff we both watched or listened to like the bad girls club, one direction, k dramas, and k pop and that made me more upset because why would he tell me that I have anything in common with the girl he cheated on me with I went to the living room because I’m not going to watch it.

But he thinks it because I don’t want to watch what he likes when that’s not the reason at all he said there it’s over you happy and he keeps asking me what’s the deal about it he doesn’t understand why I’m asking him not to watch the YouTuber.

AITA for being upset over this?
