confused to the max someone help me

Been talking to this guy for about more than 6 months and all we do is text each other and see each other once a week, but he always FaceTime me when he gets out from work. He is going to school and working. The only thing that I don't understand is why he has not ask me out yet. Everything is going well between us. The only thing that bothers me is that he hasn't went further maybe is because he doesn't see me as his girlfriend. All we do is go half on hotels kick it and call, text and FaceTime. I haven't met his family neither did he met mines, but they know of me. Idk girl maybe I should wait and see what happens. I don't want to look desperate what do you think ? He playing games or what?
