Should I distance myself or keep talking to him?

Hello everyone. I'm friends with a Scorpio male. We're not official yet but we're talking through Facebook long distance. I know it might seem complicated but I don't think it's impossible. My problem is that he send me mixed signals and I feel like I'm going crazy. One day he's really sweet and flirty and the next day he's cold and mean. So I really don't know if he seriously likes me and he makes me doubt a lot. I booked a flight to New York and I'm going there in August. That's where he lives and the reason why I'm going is because I also have family there. I met him there a year ago while I was visiting my family (I live in Colorado). Since I'm going to New York again it's my chance to see him and I've been looking forwards to it!!! The problem is that he keeps hurting me when he's cold with me. For my graduation he didn't acknowledge me and it made me feel like he doesn't care. But other times he's really sweet and calls me beautiful. So I'm going crazy trying to figure him out and I'm scared of getting hurt. I've thought about keeping my distance from him so I can move on because at this point I'm not sure if he really likes me the same way I like him. If he's really interested, he'll find a way to contact me. But it's this a good idea? I'll be sad because I'm literally DYING for him but I don't know what else to do. I also think I'll feel bad when I go to New York because that's my only chance to see him in person again since we live far. I like him a lot but I'm unsure about his feelings for me. Should I keep talking to him or distance myself?
