I find it curious because I bet if you had cheated on your W with another women, and then moved out to be with her, and had S4 start calling her mom, your W would go ballistic.
I think this is what drives me most crazy about this entire ordeal. A few years ago when she was pregnant she thought I was cheating and cursed me out and even had her whole family involved to come kill me.. Yet now she treats me like I'm just the dog crap under her shoe and just "too bad, so sad.. marriage is over" and even early on I tried to get her family involved because this guy is a known psycho and they just went monotone "Not getting involved in this. Not getting involved in this. Shes an adult." and have even allowed the AP over at their house numerous times even when S4 is there.
And we arent even divorced yet.
It's the most helpless feeling I think I have ever experienced in my life.
