Afa, yes, your first thread is locked. Hey, happy birthday.
Hang in there and wait till tomorrow to think about what to do next. Today is your day!
This is what my coach would say: When your W says she feels good, you say, "well, that's great. You know what? I know what you're talking about, because I feel pretty good too."
You should address the OM thing soon. Just a calm, "Hey, I heard you brough the OM to the house the other day, and this wasn't what we agreed to do. If that's what you are going to do, you'll have to move out of the house. Think about it and let me know."
Happy B-day again. Things will turn out well for you.
