there are organizations all over the U.S. that are set up to help out this kind of situation…. emergancy & long term housing. If you’ve been paying her rent already, you have the ability to pay rent somewhere eles. Sliding scale housing does exsist for low income folks. Please look into it. It sounds like if you & your bf can become self sufficient, (even if you need help at fisrt) you will have a more stable home to bring your child into.
I suggest doing an internet search for local agencies who can help in this kind of situation.
