Again, I just don't think that's silly in the least. A baby is a big, big deal... of course you want it to be with your life partner, totally reasonable. Maybe hold off on the poly disclosure. Like, really, set all the dating desires aside, and *just* seek to broaden your circle of friends. Having a wider social support network never hurt anyone, and a friend-of-a-friend can be the best way to meet a new partner. But if your current search is leaving you so frustrated and unsuccessful, give it a break and start anew when you're feeling refreshed and have met people who aren't such douches. They are out there.
Me, 30ish bi female, been doing solo poly for roughly 5 years. Gia, Clay, and Pike, my partners. Davis, ex/friend/"it's complicated." Eric, Gia's husband. Bee, Gia and Eric's toddler.
