My BPDex showed up at my brother's funeral

[letmeout]

My ex showed up uninvited to my brother's funeral, and he knew he wasn't welcome there. He called my sister-in-law a few choice names, all because she called him an a-hole after he showed some very bad behavior when I left him.

Our sons spoke up in his defense when I complained to them about their father being there. They think he had the right to voice his displeasure at my sister-in-law just because called him some names back then.

Any ideas on how can I keep him from showing up at future events?  We have had no contact since the divorce, and our sons know good and well that he is not welcome in my presence.

Just very frustrated right now because our sons know that I am still being treated for PST from being married to that monster, or am I over-reacting?

letmeout, you are not over reacting - they are your feelings however you really can't stop him. The family needs some strong boundaries to not let him know of family events.
