His baby momma moving in

Tamera
Can I please have some real advice??? My SO & I live together, and things are pretty much good but we also have bad days. But anyways his baby momma recently got evicted from her apartment. They only have one child together but he also takes care of her oldest because he's the only real man in her life. Okay, she's 9 months pregnant (by his friend) So a few weeks ago he asked if his kids could move in. I told him we should wait til school is out and go from there cause we on two different work schedule, and we live in a two bedroom apartment (we're moving into a house in May). So last Monday he told me she got evicted she's homeless blah blah blah and she needs a place to go. So me being me I said well the kids can come but she's pregnant with ANOTHER MAN child go live with him. But seriously my answer is no because that can cause sooo many problems but I just want to know what would y'all do if you was in my shoes.??
