My wife is leaving me.

We married last December its about to be our anniversary. We found out our house has mold and its causing us to get sick. Shes staying at her moms because shes pregnant. My mom lives with us. We live on a moutain and my mom refuses to move off of it. My wife has been looking for something on the mountain but we cant offord anything. She thinks we should just move off the moutain and itll be closer to her mom and her job and theres more jobs for me down there too that got my intrest but i wont leave my mom. My mom needs me she is in really bad health. My wife said she loves our home but we cant have the baby there and if i choose to stay then we are getting a divorce because she doesn't want a marriage in 2 seperate houses and she said i can come see our kid but i cant take her to my house. I looked for houses as well but we cant offord them or not enough room. She showed me some pretty good places that we can live in but my mom wont budge she wont leave this mountain. How can i make this work? What should i do?

Update: the mold has been treated an now is so bad wed have to take the walls down its under the house in the walls and pipes.
