<human>: Can you condense the text into a few key points?

I was divorced a year ago, been separated for three.  It was brutal; she cheated on me with three different men, start abusing prescription pain killers with her latest boyfriend and had me put in jail for a week for a crime I didn't commit.

After an outrageous amount of money payed to a lawyer and a private investigator, I'm free and clear of any criminal charges and have primary physical custody of my 6 year old autistic daughter.  Her mom gets her alternating weekends and holidays.

Keeping it short, our agreement states that my ex needs to pay for half of our daughter's medical expenses and that our daughter is to have absolutely no contact whatsoever with her latest boyfriend.

My ex lies to me and says that she isn't seeing him, even going so far as fabricating another man's name to throw me off.  I've hired a PI again who got evidence that the man was with my ex while she had our daughter for the weekend, and I've got a print off of the guys facebook page showing the two of them together and in a relationship and that he lives there.  Thats on top of the fact that she pays almost nothing regarding her medical bills (I haven't seen any money in two months).

I've just dropped my daughter off to be with her mom for Christmas for five days.  This is the first I've been away.  I'm nauseated that I'm dropping her off to spend time with the this scum-bag degenerate druggy and my sociopath ex.

How to I get through this, reddit.  I feel prepared to go back to family court to address these issues, I can't live with myself knowing I stood by and watched the worst human I've ever met become a permanent fixture in my daughter's life.

This is VA, by the way.
