Its not that I'm trying to ruin anyone's life. and its not that I'm coming on to him, he came on to me! This is his idea, I'm not secretly plotting behind their back. Even though I like him, we're both very aware of the fact that this is casual sex and that he probably won't leave his girlfriend, even though he's 18 an therefore old enough to have potentially baby sat her at one point. I don't know, I'm leaning towards no, just because he's kind of proven that he's a jerk, but on the other hand, if i want to have sex with him and he wants to have sex with me, is it my job to make his relationship choices about how this would affect him/his girlfriend's relationship for him?
i did some pretty cruel and mean things simply for their amusement value when i was younger. i hope karma doesn't exist.
