Well we all survived the wedding! My niece decided not to invite her brother in law (her sister's ex-husband) to the wedding. I think she did talk to him about it. He threatened to show up at the church anyway to annoy his ex-wife, but he didn't. He did come down to my mother's (my niece's grandmother) to drop off a card for my niece and her new husband.
Ironically, my niece got married in the same church as her sister and her ex-husband. I was sitting there listening to the minister (a new one) and I couldn't help but look at my other niece, the recent divorcee, and wonder what she was thinking when they said their vows. Behind her sat her new boyfriend, well they've been together for quite some time because her marriage was over before it became official. He was sitting with her two sons.
I didn't say anything to anybody about her ex-husband not being there, etc. but my sister (not the mother of these two girls, but my other sister) commented to me on how strange it was to see the boyfriend sitting with my nieces kids at the wedding and reception and how it seemed that the ex-husband should have been there. Not that we thought he should have been invited, it's just strange to see someone else in his place kwim?
Just thought I'd post a little update in case any of you were wondering how it turned out.
