Okay so I know this sounds crazy... but I'm curious what some think. My fiance and his ex girlfriend have a child together..I have two children by my ex husband... my ex and I are not able to co-parent due to his ....inability to do so, but my fiance and his ex are still friends. So much so, that I too- speak to her regularly. She lives with her boyfriend (whom she plans to marry as well). We have all of the kids parties together... All 3 children even have sleep overs at her place... etc.
We all get along very well.
so, invite or don't invite to the wedding? Call me crazy, but who else would I ask?

is it offensive to invite her?
