So a few months back i commented on one of her friends that is hot, and she heard it and got mad. We talked and we went past it. The relationship was still good and we had an awesome time for the last two months after that, but today she broke up with me because that incident has been playing in her head and since it happened and now she finally snapped and cant take it anymore. She said that she tried but just cant trust me and will never be able to trust me again and we have to break up. She is always worried when i go somewhere and cant trust me. I even showed her messages with my friend where i said that i would never cheat on her but it did not help, she will never trust me and that is final. I feel strange. I know i fucked up but i mean, is it all on me or does she have some deep rooted issues?
