MM, remind that little girl she will be ok without him. REALLY. He hasn't really been there for her in two years. She is ok. She is going out with friends tonight. She can handle this.
Meanwhile, ADULT MM needs to protect herself financially.
NO EXCUSES. Get an attorney in place to protect herself.
That means shopping and retaining an attorney.
