Ex wife's bad parenting decisions
My ex wife lets our 12 year old son smoke pot. I have seen it, my current wife and my sister have all seen it. My ex wife also showed my current wife pictures of her and her current husband out at sex parties. Basically I think they are swingers. My ex wife has called me several times saying her husband is having affairs, she said she told him she was leaving him. She left a message on my answering machime saying he was running around the house with gun threating to kill himslef if she left him. She also said he was doing this in front of our two children. We have been divorced since 1999. I an not in my two kids life that I had with her but I also don't think this is appropriate behavior. What should I do?
