Hey! 
I'm not in this position.. (yet)
But it is something I thought about. If I was to marry again, would I or should I invite my ex-husband..?? I know it depends a lot on the type of relationship you have post break-up/divorce. Mine was smooth. No drama. We are cordial to each other now, but not 'best buds'..
Do you think it'll jinx your new relationship to have an ex partner?
Just curious if anyone has been in this position..? And what they did?
