I cannot get over that you're FB friends with the OW. Block that woman! You deserve to post without that weirdness. AND you're friends with the woman your WAH wants to get with? What is this? Is he trying to get with all of your friends? Gross. It's almost incestuous.
Blech!
It's time to thin the FB herd and get rid of a few people so you can post without all that grossness. You deserve that!
On a separate note, I don't think anyone can blame you for losing your motivation and wanting to run free in a beautiful spring meadow. It sounds amazing but from our perspective it looks like a beautiful meadow but when you look more closely, there's crab grass and gophers everywhere.
Keep watering your lawn. Pull the weeds, plant some flowers, invite the hummingbirds and the ladybugs because your garden is going to be a healthy garden with or without WAH's assistance in tending it. It'll weather storms and scorching heat, hail and tornados. Just keep tending.
