I am in the same sort of boat, but was finally able to get the state department of human services (child welfare) involved and it has made a world of difference. My ex left our 9yr old son alone for 2 hours in the middle of the night. My son called me but I could not get there before his father returned home. I had called my ex's parents because I knew they could get to the house before me. Long story short, DHS interviewed all of us and determined a "true finding" of neglect and have opened a case for our family. If my ex doesn't go along with what DHS requests, it will not look good for him when I take him back to court to request supervised visitation. If he goes along with DHS, it will only be for show and for a short while, knowing him. I now have well documented facts from an independent agency (DHS) to use in court to change visitation. This is alot of clout, not just my word against his. I'd encourage you to contact your state's child abuse hotline. Also, keep in mind, if you know of abuse or neglect and do not report it, you could possibly be cited for "failure to protect" if someone else calls the hotline about your situation and lack of action. I know that in my case, I could not live with the guilt if I did not report this and then something really bad happend the next time.
