Please help. l need to know what he wants in our relationship?

I would casually bring it up to him and just say to him ive been thinking a lot about this lately and i was wondering what you want in our relationship. when you can talk openly about things it makes for a stronger honest relationship. i wouldnt mention the dad thing till you find out what he wants. if he does want to move in and he does see this going into the future then maybe tell him a little later once you know thats for sure thats what he wants. if he says he wants to wait then dont say anything your right it might make him run at the thought of responsibility
