I've been sued for custody of 12-year-old

Georgia. I have an attorney, but he is out of town until Tuesday.

For 8 years, I've had primary physical and final say in joint legal. I have always been VERY liberal with visitation (roughly 60/40 split with him). However, he has NEVER worked with me on parenting issues; i.e., age-appropriate movies, allowance, discipline, etc. He feels he can say anything he wants to his daughter and do anything he wants in his home and he does not have to talk to me.

He is pulling out all the big guns in the manipulation of our daughter. She has read the court papers, she feels I am punishing her for wanting to live with her dad, she was encouraged and did not get me a Mother's Day present. I started family counseling for me and her when this issue arose and he has sabotaged that by calling it "punishment".

His case for custody is:

1. I smoke. So I'll quit. I never smoke in front of my daughter, but I'll quit.
2. I drink. Okay. Maybe once or twice every other week I have a couple of glasses of wine at home. Because he doesn't drink at all, does that make me a drunk?
3. My mother lives with me. She moved in 2 1/2 years ago. She lives downstairs in a complete apartment with full kitchen, separate air/heat. No conflicts in home since she moved in.
4. He is more involved in her extracurricular activities. Up until 2 years ago, she was very involved in dance which I carried the sole responsibility for. He and his wife then became her soccer coaches. They increasingly made it uncomfortable for me at the games, so I did not go to any games this year.

I guess I would like some input from others on how strong does his case sound. My attorney says "not a chance", but he hasn't seen the papers yet. I still would like to hear from others that have some different perspectives. Also, I would like to know what I can legally do to stop his manipulation and deliberate interference in our mother/daughter relationship.
