thank you for all your advice
i've done a bit of reading and i was wondering, since he's 15 years older, been paid off his job and practically homeless would things not look better for him for maybe a 60/40 split or even her having to pay him!!!
his wife is younger, more likely to get a job in her profession, has a roof over her head in a permanent address. where my dad is squatting at friends houses and he has now said he'll pay her rent for the next 6 months in the hope that once she settles they'll get back together!!!
he's tip toing around her meeting all her needs
if they live seperate lives by the time they pay 2 rents, bills etc their money will soon go but together they can have a comfortable life
their house is being rented out and at the moment thats the only money he has and she now wants that rent aswell.
