My ex-wife is not letting my have my daughter on set visitation. It originated because she thought I was smoking weed while I had visitation, but I was not. I have smoked weed in the past but never when I had visitation and certainly not around or in front of my daughter. Can she take away my visitation/rights because i've smoked weed even though it wasn't in the presence of my daughter? Would I be in the right to file a contempt charge for not allowing me to have my visitation days? Does she have a case?
