Ex and I have 3 DC 5, 7 & 10.
We have been separated for 2 years.
So far we've had a fairly amicable arrangement re sale of house and custody of DC.
He has DC 3 nights a week.
I realised a month ago he should have been paying a lot more maintenance than he has been.
Since I pulled him up on it he has decided he wants 50/50 custody of DC even though he works full time.
He owes me £600 in unpaid maintenance and has so far refused to pay as I won't agree to 50/50 custody.
I am really struggling financially and have less than £100 in the bank. I need to get car insurance as it ran out a couple of days ago but can't as have no money to pay.
I have explained this to him, that I cannot use my car and he is still refusing to pay.
I left him after I had an emotional affair. He had emotionally abused DD for years (shouting at her, leaving her out) and had an alcohol problem. He assaulted me when he found out about the affair but was never charged as he denied it.
