What is reasonable and what is not?

[Startingover2]

I don't want my child with him either if he is drinking, but how do you prove that??? I am starting to get nervous.

He is a part time dad to his bio kids now. They are 13 and 10 and are with him 2 weeknights per week. The oldest really doesn't want to be there much and the youngest is still rather defensive of him. I think he likes it just the way it is.

I guess I better get some info on what my rights are and what I need to do. Doesn't look like he will step up.
