What legal rights do I have now that I have been forced to leave my home with my husband and child?

I was told that I was no longer welcome to my mother’s home and that I had to leave because I said something she didn’t like about her 40-year-old son. Her son is a drug user who uses heroin and has several law enforcement ins. Twice he’s been serving prison for cocaine and robbery. She let him move in with the understanding that he’s already using and selling. I’ve spoken to her a few times about my concern to have him around my kid. It falls to the ears of death. I was told that I wasn’t going to be disrespectful of her at home, and that I needed to leave. This wasn’t an excuse to drive me out of the house I shared with my family for two years. I’ve been married for 13 years, and I’ve never been cruel to her ever before. So long story I got a kick out of my home to protect the well-being of my kids. My husband never came to my aid, and he remained behind with his mother. Now he’s not going to talk to me about what happened. I just need to know his marriage plans and how to proceed. From this point on, is this abandonment?
