I think your feeling this way because he is showing that he is a "commitable" guy. We (people) always want what we can't have!!! He's showing he is a man who can be committed and it's driving you wild. If you think it's more than this and you feel like you have to tell him or your heart will hurt forever and he is your soul mate than say something... otherwise wait. If he is your soul mate fate will connect you. Best wishes!
