I 35F and married to my husband 36M. He's a good husband and father. His mom and I just do not click. His mother moved in with us without permission last year. I just managed to escape her and get her out because she went back to her home country for a few months vacation.

Well in her home country, she got a full medical work up, including whole body scan and they found cancer. She wants to come back to us and have treatment here. I couldn't stand her before and had told my husband she cannot move back in for any time (even "short period" - which is what she said last time and it lasted a year).

I told him I'm sorry for the news. When he suggested MIL move back in so we can help out and she has no home (because she sold hers and moved in with us - again without permission). I told him, no, absolutely, she cannot move in with us, and if she moves in, I will move out with our kids. I told him if he wants to live with his mom, he should get an apartment and move his mom in with him - while I stay with the kids.

He said I'm abandoning him at his lowest as MIL is his last living relative. I told him I'm not abandoning him, I'm there for him but I refuse to live with MIL. Am I an AH?
