So the wedding was this weekend. I'm not sure what was up with MOB, but she was super relaxed and friendly. Complimented my dress, very chill. At the reception she even took a spin on the dance floor with Partner!
Pregnant friend was in fact showing at the wedding. And her and bride had picked a lovely dress that allowed bump space and coordinated with ours. MOB told her she was glowing and asked lots of questions about how she was doing and if she was excited to be a mom. All upbeat happy questions, not prying noisy questions.
There were a few confused friends of MOB about us being engaged. Nothing rude, mostly "But...you're both women? Engaged to each other...?" and yes the "Like Portia and Ellen" trick did work! I'm gonna remember that in the future. After that was cleared up everyone was perfectly polite and wished us well.
Over all, nothing caught fire, no one got in a fist fight, the cops weren't called, and I only saw one girl in the bathroom crying. And she was 3. So in my book, excellent wedding!
There was an open bar. I'm think that might have contributed to MOB's high spirits for the night.
