I don't know what to do?

Last year I became really close friends with a German exchange student and really he was my only guy friend, which is weird because I'm a guy. When he left I felt kinda empty because he was the only person I could chill with because my girl friends all were obsessed with drama and shopping, and even though I was annoying we spent a ton of time together. Due to the fact he was a foreign exchange student he left to Germany and we barely talk anymore. This year I decided to become friends with a guy I was sorta friends with last year. I pursued our friendship and we became pretty close. We hang out, but I'm the person that always makes the plans due to the fact he's pretty quiet and hardly hangs out with people. All my girl friends think I'm obsessed with him, but they don't understand how important it is for me to have a close guy friend. We talk about sports, and our lives, and even clothes, but our friendship really means a lot to me; I love him like a brother. I feel like I value our friendship a lot more than he does even though we spend a ton of time together in school. School just finished and I've tried to contact him and he hasn't responded yet, but he's spent a ton of time with his ex-girlfriend. I don't know if they're getting back together but we became good friends when they broke up and he would always talk about how she's crazy (one time she clawed his neck). I haven't done anything bad, I feel like we're drifting apart. Any advice on how to mend our friendship because it really means a lot to me. Please help, please don't make fun of me: I'M NOT ATTRACTED TO HIM.
