Job, I worry about others thinking they are "helping" xh to right a wrong. After all, he fully believes that I am the reason he has less money than he thinks he should have and that his relationship with the boys is in turmoil. He also believes that he was unhappy and suicidal because of me. He doesn't see or admit any connection between his choices and his life and relationships. That's amazing to me.
I'm concerned about his gf. I have no idea what she looks like, so wouldn't know if she drove by my house. I've read enough stories here and other sites about A partners flipping out on the x spouse. Thankfully I live on a quiet cul-de-sac with neighbors who watch out for one another. One of them is an FBI agent and is always on the lookout. My neighbors know xh is not welcome here and would alert me if they saw him or anyone around my house.
