Hi everyone, it's my first time posting here (or anywhere) about this topic. I've never been too keen on forums but I have no one to talk to about this and I really need an advice/a new set of eyes. I'm 19 and my boyfriend is 20. We've been together for 3 and a half years, we've been very mature about the relationship and it was only getting better. We communicate our problems and feelings the correct way. Now, my stance on a s/o looking at pictures of other women and doing his ..thing.. to them isn't the best. I was never trying to be controlling but I'd ask him kindly if he could unfollow girls that he didn't know/spoke to. However, a specific girl was in his searches on Instagram yesterday and my heart sank. I already knew what it meant. The same girl he unfollowed 3 years ago. He remembered her user, searched it up, did his thing. I immediately started crying while he was just there..looking at me helplessly. After we both calmed down I tried to get any answer out of him, but I'm not sure if I should trust what he says. There was a time when I saw random Reddit nudes on his phone while he was scrolling through his gallery, hurt me a lot but I gave him a chance. But this to me is different, this is a real person that he could go and meet or talk to, this isn't a celeb or a pornstar..His explanation was that after our argument a few days ago, he was stressed and needed to do it, he said it was a dumb thing to do and that he felt gross and awful immediately after along with other sappy things he wanted me to hear. I'm not sure why some men do that, or if they even do. Is this a valid explanation or am I overreacting? The thing that bugs the most is that he has a whole folder of my pictures, and even if he didn't want to look at me then he could've used porn or a celeb, not someone so easily available to him. The girl doesn't look anything like me, in my opinion she's prettier, has a better body, bigger boobs and everything that men would generally find hot. I'm glad I'm not in a situation where he actually went and did something physical with someone (but now I can't be sure he didn't already without telling me) but this still bugs me so much that I don't know if I should stay. My confidence is gone, my trust and feelings towards him have completely changed, I see him and I feel disgusted, I don't know if I'll ever be able to kiss him or be intimate with him again knowing what I know now. All I think about is him looking at her face and getting off to it, and that's the worst part, it was JUST her face. He said he hates himself for it, feels disgusted and feels like throwing up. He showered me with what seem to be genuine compliments, everything that he loves about me, every detail. He said many comforting things since then but after multiple chances I gave him I don't know if I should believe that. I don't want to get hurt again. We had boundaries, he knew every single one, he knew how much I hated people that do that, he knew how much it would hurt me if he did that, he knew it all. If I accidentally didn't see his search bar, I wouldn't know. He wouldn't tell me. He didn't care until he got caught. He didn't deny it but he also didn't say unless it happened. He says it will never happen again because he feels disgusted with himself. He says he doesn't want me to leave, he doesn't want anyone else in his life, he said he wants to see how I'm doing every day, see me laugh and smile and hear my voice. This is such a hard decision to make since we've basically grown up together through our toughest times. I really don't want to hurt myself more, I can understand finding other girls hot, I find other men and women hot too!! Of course! But I just can't understand having a specific person in your head for three years and getting off to them while you have a whole girlfriend you have pictures of, who you supposedly love and don't want to lose.. Any eye opening advice would be awesome..:(
