OP here: I'm definitely not going along house-hunting, and have not even really looked at the brochures he is showing me... I get the sense that I can't force a conversation on him, and have to keep some distrance so he approaches me with the conversation... In the interim, until HE asks to be exclusive explicitly, I will date other people as well as him.... Becuase I can't force a decision on him, and think that wil make me look needy.... I just wonder if showing me this house stuff is his - less direct - way of telling me something, or if he is just testing me....
This relationship sounds way too vague and uncommitted. Frankly, I am surprised that you--a divorced mom--would put yourself in such a passive position. You break up, get back together and yet you cannot even have a basic conversation about the direction of the relationship and commitment? You are in a relationship where you think he is 'testing' you? The relationship doesn't sound very solid, but more than that, you sound like you have a lot of maturing to do. By this point in your life, you should only be dating someone you can actually communicate directly with about matters of importance. Tiptoeing around, wondering what he's thinking, being too scared to be direct, not even knowing if you two are exclusive--this is typical of recent college grads who are entering the dating world, not middle age adults who presumably have matured past that point.
And, to answer your question I think this guy is wasting your time. I think a man who is in his late 40s and has never been married and is a "Mr. Big" type will be very unlikely to make any commitment, particularly one to a woman with kids. And if you two haven't even had a discussion about exclusivity, you are very ,very far from moving in together. Or you should be. I'd have a real sit down, 'state of the union' talk and see what happens. I'd also practice being direct and forthright about my desires, hopes, and expectations in a relationship much earlier on.
