I'm so lost

Seriously considering filing for divorce, I'm 25 weeks and my mom is getting kicked out, she is a hoarder and her house is insane. It's been just her and I cleaning and packing my husband is A truck driver and finally got a weekend and new how stressed I've been and chose to go spend his only weekend get trashed with his brother who has been texting him about all the girls he's been screwing since his wife just left him. As well as my husband agreed before not to drink because he's used at an excuse as to why he cheated years ago. As well as he has ignored me the whole weekend. I'm scared to be alone but I already feel so alone I should just cut ties so my daughter doesn't have to see me be hysterical once she's here and he keeps pulling his shit
