Dear Kay:

“I would need to think how to ask that, without sounding like I want to get married”- you can say before you ask: I want to get to know you better, to get to know what you think about this and that, that’s why I want to ask you: __________________?

“he has a point, we do not really know each other well”- question is, does he want to get to know you better and does he want you to get to know him better. If he does- he will be glad to answer your questions (that’s how you will get to know him better).

If he wants to know you  better, he will ask you questions about what you think about this and that. Did he ask you questions about what you think, and what you want for your future, any such questions?
