Boy Problems

Okie so I have a problem. So let's just say that I have liked this boy for what 1 year ( close to two ) and yea, we date 3 times and we're best friends. Anyways I liked another kid. And we had a thing. When we had that thing. It didn't feel right. Like it just felt weird. I mean with that other kid he never like said things like your cute, blah blah blah and this other kid did. And it happened with my other ex too and I don't want it to happen again. Please help?
