Me (21f) and my boyfriend (21) of 3 years have a relatively active sex life. So when I found out he was watching porn and jerking it to other girls, my heart broke. It makes me feel so inadequate that he looks at other (skinnier) women the way he’s supposed to look at me. I asked him to stop yesterday and he got angry and told me that it doesn’t mean anything, but it means something to me and i told him that. He basically said “whatever” and that was that. This morning i caught him watching it again and when i confronted him about it, he said i was being bitchy. I need to know, AITA for getting upset?
