Dude, if you even want a chance of getting some constructive advice on this site, learn to seperate the wheat from the chaff.
While I certainly don't agree with what everyone on this site says, I have also gotten some really good advice because I don't make each disagreement a pissing match. My Granddad used to tell me that the only thing that happened in a pissing match is that you got your pant legs wet.
Don't go down that road man. There are a lot of good people on here that are willing to share their experience, strength and hope. But if you're willing to engage in a pissing contest with each person that gives a dissenting opinion, people won't even bother to respond.
I hope you find what you are looking for in the divorce process. If Mom is a bad mother, present the evidence as a truthful fact. Don't make stuff up, it will come back to haunt you some day with your daughter.
My SO's ex has told his daughter all kinds of bad things about the SO & I. As she has gotten a little older and seen with her own eyes what is really going on, she is beginning to question the veracity of what her Daddy is telling her, and losing respect for him each time he does.
And remember, whether she is a bad Mom or not, she is still MOM and always will be.
