Before you flip out on me, let me explain. Our flower girl and ring bearer are my niece and nephew, my brother's children. My brother has been divorced for a few years now and resides with his girlfriend, 30 minutes away and never sees his children [sad, but not my point]. My point is that I have to go through my ex sister-in-law to see the children and she has agreed to let them be in the wedding. Actually, she was eager to allow them to be involved; we get along fine now that she and my brother are divorced. :]
So my dilemma is that I'd love to invite her and include her, as well as her new love interest, but I'm afraid that it might hurt my brother's feelings. I'm absolutely SURE that my ex sister-in-law would understand. Perhaps I should sit with her and tell her what I'm feeling. Full disclosure is always best.
