Forgive me for being blunt. It seems like your wife has regressed to the age of about 13.
Quote: Right now she is in her room looking at pics of OM on her computer
How is she with the kids? Has she stopped spending quality time with them, in order to have more free time in her room on the computer? This isn't a real relationship, frank. I don't know what it is, but it's not. Heck, my H. and his o.w. have a much more real R. than this; that's the truth. She's REALLY lacking something inside and this obsession with this faraway OM has gotten a hold on her. Do you think she chose to not attend the party because she wants to stay online? Just wondering if now she's going to stay in her room all night on the computer. Does this happen a lot? I am sorry I'm not much of a help here. We need the big experts to weigh in...
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
