While on weekend visits, my 16.5 yr old daughter has been allowed to go out drinking and partying with her 20 yr old step-sister, where she is also being exposed to drugs and at one point my daughter supposedly watched her have sex with some 19yr old. I have text msg confirmation and a positive urine test that provide evidence this is happening. I also have proof of text msgs between my 16yr old and her 17 yr old step-brother that they're smoking pot or something. I have advised my ex-husband of the situation and he disregards it but points the finger at me as if I've taught her this behavior. What's amazing is he is a supervisor with one of our local police departments. Is there anything I can do to prevent this from continuing and prevent my ex-husband from exposing my 10 yr old son to these elements as well?
Yes. File a motion for modification that asks for his visitation to be curtailed, supervised, or eliminated completely. And ask for temporary orders.
If you live in the Houston area, contact me for a referral. I absolutely agree with Mark Dunn.
