im so glad you are doing better. My opinion is that your relationship with this guy ...as you described it....is one that would have never gotten any better. Threats, manipulation....intimidation....pounding on your door and causing a scene.... you need to just move on. Any judge worth their legal salt would ban this man from seeing his children until such time comes that he has proven he has gone through and completed Residential Treatment in an alcohol in-patient treatment center and completed a probationary AA meeting program proving a certain determined length of sobriety. Leaving him was the right move. You need to take care of YOU and those precious children.
