[PITSTOP]

I have a million and one things I could ask on here but here goes just a couple of things: Getting divorced at the moment and my ex has asked me to change the mortgage from repayment to interest only to bring the cost of the payments down as he says he is struggling to pay. His girlfriend does not work put picks up more money than me yet I am expected to pay all the bills for the house, all the childcare for our 2 children as I work full time and anything else the children need i.e. swimming and dancing lessons.
Why should I do this for him? he has not offered to give me any money towards childcare over the summer holidays and has used all his own holiday up going to Egypt with his girlfriend so he can't even look after his own kids during the holidays. He keeps phoning and giving me abuse as I have refused to sign the forms up until now, but I feel I am being bullied.
Please advise
Just wanted to add:
He will not pay maintenance for the kids until he stops paying the mortgage he says that's his kind of maintenance!
