Thanks everyone. As expected there’s a very wide range of opinions.
I’ll answer your questions here…
The DC all love him. We have done things slowly. He wouldn’t move in for a while yet, we have just been thinking out loud. The DC don’t see their dad. I don’t get CM. I’m self employed and I sometimes get a small UC top up. It depends how my work goes. Yes if a second adult moves in I’d lose the 25% council tax discount.
We are committed and will be looking to live as a family. It won’t be cramped - the DC all have their own rooms. I’ll have to declutter my wardrobe - no big deal. There’s plenty of storage, a garage, a double drive.
From my perspective, I’d lose the small amount of benefits I currently get but I’d have all my bills paid. He’ll help buy food, we might set up a household account and pay in proportionately? He has been very good around the house. He doesn’t leech, he cooks a lot, he shares the chores, he’s very hands on with the DC. He is making our life a lot nicer - keep in mind I was a single parent to 3 young DC for years, with no coparent and no CM, the eldest DC is only just 9. We’ve spent time with his adult DC and it’s so lovely to feel part of a family again.
I don’t think I could charge him rent. I think the amount my bills come to is roughly what his current mortgage is, so he wouldn’t be better off month on month (although I appreciate he would increase his capital, I get it).
The idea is by living together we can all save money?
We can’t move into his, it’s not big enough and not local enough. The kids have had enough to deal with, this is home now. I’m only going to do it if he continue to enhance our lives in the next year or so.
