Me and my partner are currently considering moving in together. I own a house, he's renting so he'd give that up and move in with me initially, with a view to buying somewhere together further down the line if all goes well.
I have one child, he has three. We've started discussing how we'd split bills etc and I'm struggling to work out what I think is fair. Initially I thought everything should just be 50/50, but now I'm not so sure.
I have a mortgage, he's offered to pay towards that but does that give him any entitlement to the property, or would you just see it as 'rent'? And I'm not sure whether he should pay more because he has more children than I do?
Just as an extra point- we both have our children 50/50, so I don't ask my son's dad for any maintenance, but he does pay his ex wife £500 a month. I'm genuinely not sure if I'm reasonable saying this but his ex works part time, I assume part of the reason she can afford to do this is because of the maintenance she gets.
Me and my partner both work full time, so I can't help but feel I shouldn't be paying half of everything when there are four of them, I almost feel that by doing that I'm funding his ex wife?
Any options/experiences welcome, I honestly don't know the best approach.
