"(including his child from another relationship who I haven't mentioned)..."

That's where I mentioned the other child. She only comes in every 2-3 months because she lives out of state with her mother. But I still assume responsibility for her a bit when she's here. I'm more than happy to welcome his other child into our home, I love her and try my best with her - I do all this, yet he regards me in the way he does - no proposal and no sharing/merging of assets.

How seldom the child is with him is only part of it - he is probably paying support. Maybe through the nose.

Don't rent out your house! Get female roommates. Or just one. INTERVIEW carefully. Do not use craigslist. Use a local newspaper and notices on boards in stores, and word of mouth, very locally.

Interviewing for the whole house would be scarier, I think.

If he is on the birth certificate, then go to court for support NOW. In fact then maybe you can keep the house. Do some very deep numbers.
