My ex wife is an alcoholic, both of our children couldn't cope so moved out when they were 16-17.
Once my daughter left at 16, I also left and went to live at my mothers, leaving my ex wife in the home.
She lived there, I paid the mortgage, and she paid some of the utilities etc.
After about 10-11 months, with mounting debts, she moved in with another man.
I then moved back in, and got all bills etc up to date and lived there for approx 18 months.
I have since met someone else, and stay at her house.
The house has very little furniture etc in it, but I keep gardens done and maintain it.
Hope this clarifies situation.
