Living together / Second marriage

[Hinkero]

I'm in a relationship with a lovely older man (40s/60s, the age now isn't an issue). I have primary school aged kids, his are grown-up.
We're talking of living together. He wants his children to inherit his house etc. as do I for mine. He has said, rather than sell-up and buy a house together, he could move into our house. Rent his and the rent to pay all bills from a joint account, even paying some money into an account for myself and kids so that I can give-up work if I wish. (-lovely idea but I work and want to continue too, to support my children).
Opinons please, is this a good plan?
He's also spoken of marrying in the future if things continue to go well. I like that he is thinking of commitment. However, I'm not sure a 2nd marriage with young children is such a good idea (we are both widowers and own our own homes).

I think the idea of two separate homes for reason of inheritance is a good idea. That's what myself and partner are going to do. Tell him you'd rather work for your own independence. Regarding marriage I personally don't see the need for it second time around but I know some people want it. Do whatever you feel is right m. How long are you together?

Marriage is up to you, I'm still on the fence myself. For finance make sure you have professionally drawn up wills as it's complicated and if you do choose to marry get a prenup too to be safe

It's sensible to keep houses separate, though I'd prefer a bigger house for us all. Which would mean selling both. I had thought as tenants in common to keep it more separate. Equally if things didn't work we'd have to sell-up and I'd need to buy a smaller house again.
With the giving up work, I've said it's a lovely idea but I need to work for the children. (He's fine with this, it was just an option).
I like the idea of marriage, not 100% sure on the idea but it'd be some way off in the future.
We've been together just over 2 years.
I'd need to take legal advice with living together and marriage if we got to that point.
Our houses are worth much the same. It's my only asset. He has more assets, decent savings, pension and earns alot more. I earn a reasonable amount but need to sort my pension (another reason to continue working).
