What should I do????

I would say that if you two are not living in the same home but you are still there, you should pay at least half the house payment. You should also pay your own bills as well as that effects you, not him.

Good luck and best wishes

Wow sounds like what I was going through.  Are you both still living in the house?  Did you both share the mortgage payment before the split?  My ex and I both shared the mortgage payment and bills however before the seperation I ended up having a financial crisis.  My car died and I had no transportation to work or to pick up our youngest daughter.  Ex knowing this he still wouldn't help me with the car situation or picking up our daughter.  He kept telling me to leave and threatened to throw my things out.  It was a nightmare living in that house for me and my kids so I told him I couldn't contribute any longer until I was able to get back on my feet.  He still got on me about it, stopped paying the mortgage himself and the bills, took the money from our joint account and closed it.  Not too much sooner after that I had to leave the home because the living situation was unbearable.  He continued to live in the home, didn't pay a dime on the mortgage and let the house forclose.  Here is the kicker.  He lied on his financial statement to the court saying he made just as much money as I did each month except his take home is less than what mine is and he pays all the bills and the mortgage.  So he is trying to prove that he cannot pay any child support, maintenance or anything.  My advice to you is keep in contact with your mortgage company and ask if he has called in and spoke with them, see if he's made any payments.  Get proof of this so the courts can see that he has been making payments.  If he isn't making payments then it will prove that he can afford it in some way.  Just write everything that is going on in a note book should it happen to come up in court.

For me because we are in transition, I have to pay a certain amount to her until we are divorced.  Well actually until she refinances the house.  So yes, our attorney came to an agreement on how much is paid and by who.
Best wishes.
