I did the right thing, why don't I feel better? related.?

For the last 6 months about I decided I didn't want to have with someone unless I was in a meaningful intimate relationship with them. So I stayed out of the dating scene also so that temptation/confusing would not occur. But 2 weeks ago I met a guy and for the first time in 6 months was actually interested in him. We went out a few times, and we just kissed alot, but he was respectful of not putting his hands on my backside, or trying to feel me up in the movies or anything. But he kept bringing things up like "I can help you in the shower if you need" or "I can come over and tuck you in tonight" "Are you going to try on some lingerie for me?" he made ual comments like this and I just shot him down everytime. Well, when hes not with me hes sweettalking another girl who dresses like a slut. I'm really hurt now. I'm doing the right thing by sticking to my beliefs, and guys say they don't want slutty girls, so why do I feel so sad/bad?
