leaving behind ten years

I just moved across the country for a business venture with my boyfriend. Leaving behind 10 years of a place I called home. To "temporarily" live with him, and his parents. Our property isn't ready till late April. His parents are amazing, I'm overall very grateful to have shelter/food.
We are not getting along. Every day I'm berated, and belittled by this man child. I have no friends here, nor is it an option to go back home as it is pure chaos there. The 3 job offers, and opportunities for freedom have been obviously postponed. As much as I'd love to go be with my family, my mother has an autoimmune disease, I cannot put her at risk.
Everyday is getting heavier, and I'm unsure how I'm going to keep it together.
