The Safe Families office responded to my email and said the same thing all of you have told me. If I feel that the consent has been violated, I should file a Contempt of Court motion. It really is my best (and only) course of action right now, as difficult as it will be to go back to court and see him again.
I didn't sleep last night because I was up thinking about this and the first drug test. I used a number generator to select the date of the test and it came up with today. When I sent the email to the attorney, he responded that he would tell my ex to submit to testing if that was what I "really wanted to do." This is the man who drafted the consent (and added the drug test and my role in it) and he's acting like this is something I asked for on a whim.
Sorry to ramble, but I am stressed. Plus, my family and friends are tired of hearing me talk about this.
