Sorry me again!
Its not a sudden decision, we are separating, its been decided, we are trying to sort things out ourselves, he wants to rent somewhere suitable to live where DCs to visit as living in the same house is just not working and not any good for the children, I am investigating tax credits etc.
Today he phoned and I asked him if he could give me an approximate figure that he was prepared to give me and it needs to be one that can't change (not for things beyond his control of course), I was accused of being threatening, aggressive, difficult etc. etc. - by the way we are separating because of something he has done so why is he trying to make himself to be a victim in this?
I then stupidly asked if he had thought about when he would like to see the children and he said, I haven't just stop hassling me I'm trying to work.
I think its going to be a long and winding road ahead...
The good news is the CAB and the HMRC have been fantastically helpful, if anyone is wondering who can help them in a similar situation, just give them a call!
