Boyfriend

I'm 19 and I've never had a boyfriend, most of my friends have boyfriends and have had them for a while, I feel left out as I want that feeling and part of life too:/ I've been on a few dates for example, recently I went on 3 dates with a guy, he had to go back to uni but developed feelings for another girl and is now with her, I've forgotten about him now but it just hurts knowing that that's happened... Guys seem to only want one thing from me, what do you think? :)
