My x filed abuse charges HELP

My divorce started 21/2 years ago. We set up an agreement for a 50/50 share. The day before my final divorce date my x filed bogus abuse charges against me. That was six months ago. I haven’t been able to see my kids or talk to them. She changed her phone number.

DHC won’t help, because the closed the case two months ago, but the cops still have the case open because my x got some fruit cake of a shrink. This has cost me 3000$ already. My lawyer going to fight it but I really need to talk to my kids any ideas?
