I have been with my boyfriend on and off for 11 years. He got married almost 2 years ago after i left him *supposed;y for good* but he decide to make a go at it with the mother of his child. They did not make it and I had zero to do with the demise of the relationship..I had zero contact.
Fast forward to today. We have been living together for some time and they have not lived in the same home for almost a year.
We are house shopping. He is also looking for a divorce but it seems very expensive. He thinks he can just pay her child support for the child.
If we purchase a house in our name jointly can we be forced to sell the home? Can she go after it in the divorce? We found a home and we love it but I am in fear that she will be vengeful and try to force us from the home.

We live in PA. She makes at least 10k more than he does.
If we go forward with getting the house what will happen?
