A drone flying over head? Sounds like your h is very curious about what you are doing and unfortunately, I call this spying/stalking. He can't understand why you are doing things a bit differently these days, so what better way to see what you are doing then to "drone" you. He's trying to see if there is someone in your life and that's why you've distanced/disconnected from him and his situation. He doesn't understand that you've had enough and are flying solo and enjoying life and your son. I seriously doubt that he will own up to spying on you. I had a feeling that drone wasn't just for entertainment and yes, it's going to get him into trouble if he's not mindful of the privacy of others. But that's not your problem to worry about except if it gets out of hand when he's doing it to you.
I might be wrong, but I don't think your h is ready for marriage counseling. Why do I think that? Because he couldn't even get himself together to go to the joint session when it came to your son. Your h still has a lot of personal issues to resolve before he can focus on the relationship/marriage. But, that's my two cents.
