That's a bit tricky. Seems to me like he's moving really quickly. He's also being extremely open and upfront with you, and perhaps to say, at times, a little too upfront. Sometimes there's a fine line between thinking about something and actually saying it. Yeah I get that men think about things probably a little more often than women but the thoughts don't always need to be verbalised. I'm not picking up a sense that you've discussed this much in detail with him. Maybe you could try be honest with him about how you're feeling right now. Not sure. Because I don't know how he will take it. But right now you two aren't in the same place with this relationship. And perhaps he may not be aware of the magniture of that.
