CHILD VISITATION HELP!! ARE WE IN THE WRONG?

my stepsons mother is the non custodial parent. Last month we had a court date for contempt which she filed on us and we filed one on her for not paying support (she only pays 20 a week and is 1200 behind she just had to start paying back in 09!) she never showed to the court date so her charges against us were dismissed (contempt of not allowing phone time since we had our phone shut off due to financial reasons) any way..we have another court date in two weeks that we know she will not show to. She has moved to a new city refuses to give her address, as of late last month (5 days after our first court date) she has a NO BOND FELONY WARRANT for her arrest for not reporting to her work release program (she got that because of a 3rd dui charge within 3 years she got that in lieu of jail now the warrant is to send her straight to jail for violating court orders)...her last visitation weekend no one showed up...and her next visitation is this friday..she has not contacted us in 4 weeks (phone calls go through my husbands parents and they tell him if she calls or anything) her father called and asked about this weekend but we have not returned his call since its not our responsibily to work visitation out with him. We have decided not to allow her visitation and we will not be home for her to pick him up. We feel she is a flight risk and if she took off with the child we wouldnt know how to find her. Like i said court is in 2 weeks and we plan to ask for suspension of visitation rights until all her court terms are satisified. are we doing the right thing? can we get in trouble for not letting her see the child? I mean we could just have a cop here waiting to arrest her since she has the warrant out for her, but we dont want to have that drama at our house. What would you do??
