Ok so my DH has this issue with woman staying living in the family house when a couple splits up. He's mentioned it a few times and had disagreements with friends in the past saying 'you know she'll get everything if you split up' when the woman owned the house! Also when watching a programme (Broadchurch) he's got really angry about one of the characters (Beth), like he hates her and the fact she got to stay in the family house and living with the children whilst Mark lives in a 'tiny flat, alone and without his family'. And that she made his suicide attempt all about her and she shouldn't have kept telling him to stop coming round the house etc. And that it was her choice to split up so she should have moved out.
Just wondered who's being unreasonable. I think it creates stability for the children if they stay in the family house and if you don't want to be together, then someone needs to move out and if the mum is doing more of the childcare it makes sense it's the dad, although it could be shared. Not sure where I'm going with this!
