Any decision like that is going to involve weighing the pros and cons of each path.

What are the benefits of staying?

What are the disadvantages?

What are the benefits of moving out?

What are the advantages?

If one of the things you are looking to accomplish is to "send a message" to H, that he better get it back together or you are gone, then carefully consider what you're going to do.

That message you would be sending is a "one time event" -- it's sent, then you can't send it again. If you move out, I'm guessing things will be harder financially -- and that's a recurring event, every day of every month.

Plus, you obviously risk that the message won't be heard or heeded the way you wanted. That feels like a "lose lose" to me, you made your situation worse and got nothing in return.

These are just thoughts based on some guesses. If you can answer the questions above, maybe you'll get some better assistance with your decision.
