My uncle got divorced about a year ago and already remarried (they were dating before the divorce), but I want to invite my aunt, his ex-wife and my cousins, who live with her, to the wedding. I have grown up with his ex-wife as my aunt, and we still keep in touch, and I feel it would be wrong to not invite her. I'm just worried about drama between my aunt and the new wife, or my cousins and thier dad. Should I invite one and not the other? Should I not invite one?
