There is absolutely nothing more awkward than showing up to a mommy group as a guy. It seems like 99% of the women there are standoffish, and 1% are flirty. I would love to find some sahd's or even gay parents in the area that would like to get together once in a while during the day and have some adult conversation! I've considered talking to some gay and lesbian organizations in town to see if they have any groups as well. The walls are closing in on me here.
You can also try this FB group. https://www.facebook.com/groups/alternativefamiliesmem/ I believe there are a couple SAHDs in the group, and it's "crunchy."
