AITAH for not wanting my husbands mother to live with us?

Aja

I love my MIL and we get along great however; I was recently diagnosed with placenta previa, accreta and Cholestasis. I have a scheduled c-section along with hysterectomy this week and very overwhelmed by this alone. Baby is coming at 35 weeks. My MIL is experiencing financial difficulties and needs a place to stay. My husband is determined to let her stay with us in our 2 bedroom apartment and we already have 2 children and our teenage son that comes on the weekend. Not to mention our marriage has had recent struggles that we are slowly over coming together. I let him know a month ago our home is too small and with the baby coming I was not comfortable with her staying with us. We move into our new house at the end of June so I proposed a compromise that she should find alternative living arrangements until we get in our house 5 bd 3bath split level and then she could stay in the bedroom and full bath down stairs until she could get back on her feet. This was agreed to weeks ago and now she has come to stay this weekend for Mother’s Day and he proceeded to tell me and her that she could stay. Then privately made it clear to me that if I refuse to let her stay that he cannot be with me anymore and said I would be cold hearted. I feel angry and betrayed by him and was at a loss for words. To keep the peace I have not spoken to him as I have a temper and need to remain calm. My MIL has 2 other grown sons and plenty of other family that could help her if she would humble herself and ask. A dear friend of hers even offered her home to stay permanently however the location is not an area she wants to stay in since it is the hood. I’m at a loss of what I should do at this point. I just want to have my baby make it through recovery and come home in peace and bond with my baby. I absolutely do not want this woman living in our small apt and I don’t want to come across as the ass hole and make her leave. So AITAH for feeling this way?
