What would you do with the three wishes? I think you have every right to contact her and ask if there could be a family night. Tell her just the one, to see how things go and take it from there. I have friends who's parents HATED each other and it sucked for my friends. The big events these friends would stress over the possible conflicts. But I had other friends who's parents got along and maybe it was just for the kids, but those friends were a lot more relaxed during those big events. Ask her, see what she says. And make the first event a simple maybe one or two hour deal.
