My daughter is three. Her mother left me while pregnant, sued me for support, and hasn't worked since several months before the birth.

I see my daughter one day + 3 hours per week.

She recently bought a house with her mother. Her mother played this same game with two men before me.

Last night, I discovered that the ex, in the process of moving, employed the support and help of the man she dated before me. A known drug dealer who is still a drug dealer.

Without a lot of money to go to court, how should I handle this? I will lose my mind before I let a known abuser and drug dealer anywhere near my precious daughter.
