I’ve been with my parter about 27 years and it’s been going down hill last 5 or so years. We have a 10 year old with sen. I want to split, dp doesn’t so he won’t move out. We only have a 4 years left on current mortgage. I’m the higher earner, I could afford the house and bills on my own but dp could not. It’s a very cheap mortgage so much cheaper than rent would be so he can’t afford to go anywhere else. I’ve been looking at rents and I could afford to rent somewhere else but I wouldn’t also be able to subsidise dp still living in our house by paying the bills so me moving out then means dp would no longer be able to live in our current house either. Both his parents are dead he doesn’t really have another option of where to live, what do people do in these circumstances? I suppose he could go and rent a room somewhere but he won’t move out but the practicality is he can’t afford to take on his he house on his own- this is mortgage/bills only without even considering me taking out equity or him paying any child support
