Although life would be much simpler if people said what they meant, it seems that most do not. If I had to guess, I'd say those guys didn't want to hurt your feelings and thought it was gentler or nicer (or easier) to say that they'd hang out again even if they had no intention of doing so. Another possibility with a dating site is that the guys were just looking to "hook up" and since you didn't sleep with them right off the bat - they lost interest. (Sorry guys - but you know there are people out there like that.) Neither of those things makes YOU a bad person or unworthy in any way.

You said you met 2 guys...that's not very many. You said they seemed nice - but were you terribly attracted to or interested in them??? Sometimes people just don't click. Maybe try a few more...or better yet, hang out in places that interest you and be brave - strike up that conversation with someone interesting... If at first you don't succeed, try, try again. Good luck!
