Most Helpful Guy
He wants to know if you want to have a relationship again, but he doesn't want you to reject him. Essentially, he's asking you to make the decision, but if that's the way he's talking, I think he's made his point pretty clear that he wants you back.
Most Helpful Girl
I think you need to actually talk face to face and find out what he wants. And be prepared to say what you want. If he doesn't offer what you need, walk away. He might just be seeing if you're willing to still put up with the same crap, he might be lonely, or he might actually miss you and want you back but you'll never know unless you talk.
