I'm sorry today was such a downer for you- I hope tomorrow is better! Maybe you should still write that letter to yourself. When you open it this time next year, it could show you how far you've come from the pain you felt today. Just an idea...
I'm glad you were able to talk to your SIL, and I hope that helped to let her in. And I'm sorry to hear about your S's situation. When it rains, it pours, huh? But I've heard that God doesn't give us more than we can handle. (It may not seem like it at the time, but that's what I've heard..) Your family is really lucky to have such a great guy like you, even if your W doesn't realize it, it sounds like the others do. Take care-
Hugs, Bunny
PS- the house is gorgeous- it really shows the care you took with it.
