I like this guy, but I'm pretty sure he doesn't like me, what should I do?

Dang girl, that's really long lol. But this is what i will tell you,, don't ever seem desperate sometimes turns a guy off or you will get him for the wrong reasons. Also keep your head high you don't need to chase after a guy that might not even like you back when a sweeter guy can be right there in front of you! :)))
