So most of last night was spent cuddling/spooning a girl. The thing is, she has a boyfriend who would probably not be too happy to find out that she was all too happy to put my hands on her boobs and that she was with some other guy. I'm not blaming her, I just think that this was really stupid of me. I would absolutely hate being in that situation, especially given the fact that I have no feelings towards her. I literally met her yesterday afternoon. I think it'd be best if I forget it happened. Ever done anything particularly stupid relationship-wise or did something to impact somebody else's relationship, for no real reason?
