I really like this guy and he really likes me, but his girlfriend.!

Okay…so I met this guy and the first day we met we instantly connected. we really liked eachother in oo1 day..!we played and talked like we knew eachother for years, and he had to leave early and I was kinda mad, but thats because he was on probation… that same night we talked on the phone. he told me who he talked to and I told him who I talked to. we began to talk on the phone a lot and text. then here comes the drama. the boy wrote me off of myspace and we talked, then his girl started writing me and im thinking its him, but it was her. the boy told his girlfriend about us and I guess she decided to go on his page. we wound up talking it out and the boy and his girlfriend broke up.! but they been in a relationship for almost 2 years. so he hasnt been calling me so I figured he has been talking to his EX. yesterday I asked him why he havent been calling me he said because he was working a lot, which he has, but I have a feeling he’s been talkin to his EX..he talks about me all the time, and he really likes me and I really like him…what should I do? how should I express my feeling for him? how could I stop making him think about his EX if he is? please help me thankyou.
