Toxic mil

So we stay with my husbands mom because my husband lost his job. We have 3 kids and I literally have no family. I’m currently trying to find work but it seems impossible also dealing with having nobody to watch my children.

My husbands mom disrespects me soo much. She yells in my face. She tells me how I don’t have shit. She tells me not to speak to her while she speaks to her son. She makes my kids cry she bashes my parents. She did apologize to me. But why do I feel mad at my husband ?

He speaks to her like it never happened. I have no where else to live so I just take the shit.. I just need somebody to vent to :/
