Like but don't like

Dear Miss know it all,

I have a problem and I don't know how to fix it. You see, I like this guy who goes to my church. He is cute and funny and I enjoy joking around with him. There are just a few problems, my friends don't like him! They think he is terrible. I get all oddly giggly around him and I catch him looking at me sometimes too. But he has a girlfriend and it's really confusing me. Does he like me or not??? and should I like him back???
