Who pays costs on a jointly owned property after divorce?

[HowToSayNo]

Just a quick question.

So, last year me and XH split. We jointly owned two houses in the same area. One was vacant so XH just moved in to that one and we agreed I'd carry on living in the other. After a couple of months I realised that I really needed a new start. Got a new job in a new area and put the house on the market (with XH's consent).

Means that he has bought me out of his house and we jointly own the other until it sells.

It's been empty for a year.

I'm happy to pay half the bills but would really struggle to pay all of them.

He says it's all my fault for moving. And that was my decision.

Where do I stand legally? Am I a terrible person for moving?
