Please read all its not long
At the start of my relationship, after three days I made the mistake of complimenting another girl, in a sexual way, commenting on her breasts, very shallow I know, my girlfriend knows about this, I couldn't deal with the guilt, I hated myself I'd never do it again
However. I seem to remember myself talking to a girl and I asked her if she would ever cheat on her boyfriend, she said no. And for some reason I had the intention to ask "not even with me". I never did ask that, as I realised I was stupid, I know it wasn't after I complimented that other girl because I'd never be able to do anything against her like that again, but I just can't remember if it was before we were together or whilst we were. I forgot this for a few months but in a daydream I remembered it again and it's killing me.
I feel so so so guilty, i love her to pieces I love spending every second with her and haven't spoken to a girl at all since then, I don't want to, I love everything about my girlfriend and I'd never cheat, she told me she wouldn't leave me if I did but i just simply wouldn't, I couldn't do that to her. She's my world, is this cheating? Should I tell her or let it go? I don't want to hurt her, please believe me
