Re: Life events in your ex's family (but still yours, too...)
Married 30 years, xw had an affair, married OM. My xSIL is only one I have remained close with (not any of the 5 brothers) and my xMIL is getting a bit senile, and isnt sure whats going on all the time.
two years after my divorce, my XSIL son got married (one of the few that still call me Uncle). I dreaded going to the wedding, which even tho it was outside, would cause me to see people I hadnt seen in two years, people who basically just discarded me. I figured that I would run into my XMIL in the reception line. So I practiced what I would say, practice my smile I would give while saying it, I practiced it over and over, tried to make it seem real, as I wanted to handle it well, as I know all would be watching and talking. Well I walked up to her, extended my hand, and said, "F! Why are looking good!" smiled, she smiled back, then realized her self and kinda turned away. I then stepped away. Easy Peasey. As for the rest of them it was simple staying away from them as they were as motivated as I to not come accross each other.
You can do it. Just stay in background, be there for who you need to be there for. Practice what you are going to say, keep it brief. Good luck.
