2 B nice or not 2 B???

I don't always sleep with the gurls, most of the time I won't cuz I feel bad,,, just like I will never sleep with a gurl that is intoxicated.....And I don't dump them either, plus I tell them if I don't want to get too serious.. It's just that they insist on still seeing me. Recently I told this one girl that we shouldn't mess around any more and we should just hang out cuz I'm leaving in 5 mo.. But she came over we watched a movie and she wouldn't let up on me... but i wont sleep with her cuz the last guy she was with dumped on her and made her feel like shit by telling her lies.. I can't do that to her-- she's too good of a person , plus she lost her virginity at 21 just 3mo ago......
