I agree with the above. I know it's been a week already, but he may need a lot more time to be able to communicate with you effectively. There's really nothing you can do if he won't talk with you.

It's unlikely that this is all happening because he's paying the bills, but only he can answer that. It's more likely that there's more underneath that he hasn't yet communicated (and may not yet be ready to communicate) that is really the source of this problem.

One thing I want you to know though: "It's all your fault" is a false statement. In a relationship, it takes two to make a mistake. Even if there' something that you're doing that has upset him, he needs to communicate this with you to resolve anything. Wait for him to be ready to communicate with you, and then see what needs to be done to find resolution. And I encourage you to come back here for support when you know more.
