You wont really know unless you around him,like I'm not strong in every subject of relationships I can get a girl but I have trouble first talking to them but I found that if you are friends before you date you know a little about each other and it won't be awkward.you will know if you are around him and if he asks you who you are dating then most likely he is interested and if he smiles at you and makes direct eye contact.
I like sports, Xbox, girls, friends, working out, watching tv, reading, playing music and other stuff. I'm not sure if all guys like doing this...
Guys like a smart girl that isn't in drama all the time I'm not saying ever but I don't like drama and a girl that doesn't listen to the crowd.
