What Do I Do?

So there's a guy I really like. I saw him a few times like a year ago but this year I joined a club and it turns out he's been there a like 7 years. So now I train with him and I see him weekly. A couple months ago at a tournament, he asked me for my snapchat. We've snapped daily ever since and We have a pretty long streak. He talks to me once in a while but just a few days ago he called my friend and my sister pretty. I want to make a move and show him that I'm available, but idk what to do. Please Help!!
