Mixed Signals

So I'm talking to this guy, whom of which I've know since I was a freshman in high school. He's a Marine and just got home from deployment. While he was away, we would Skype, message each other all the time. When we would talk it would get pretty steamy and he would say when he gets back he wants to see me and I'm going to be his (both in relationship and just a sexual manner) and he tells me he misses me. But then he tells me he doesn't want a relationship and just wants to mess around. Does he sound like he wants to be with me or am I just missing him saying he just wants to mess around?
