I lost my DH in 2020 age only 55 and now that both kids have left home, am in process of downsizing to a house I'll own with no mortgage. I'm grateful to be ok financially, and also to have recently met a wonderful man. We want to move in together, but I'm very stuck on the finances when cohabiting? He contributed financially to his 2 exes' mortgages, yet when things broke down, walked away with nothing, bless. So while he's keen to do DIY work on the house as well as pay daily living costs, I want to make sure he's safe in the event that things don't work out, because otherwise he'll be back to square one. We both work, similar modest salaries. I'd love advice on our options: 1) I pay for ALL the home improvements - it remains my house and any increase in value is also mine, should we separate. He chips in just for living expenses. 2) I let him pay 50% of DIY costs, if we broke up he'd get 50% of any increase in value (regardless of whether I sell or not - I'd just calculate it for him).
Are there other options? I want to be pragmatic for both our sakes . Any other pitfalls I haven't thought of? Of course, if it all goes well we're heading towards marriage and a whole different set of questions re: wills, inheritance etc.
