Alamo, one the reasons my W wanted the D is because she caught me watching porn one day. The thing being that i started going that route just recently because our relationship was drying out and somehow my W and I were never able to confront it and make it better.
In the whole scheme of things i would say don't worry about this one aspect.
Regarding valentine's day, I would say feel good that you had your time with your son. My daughter and W live with her parents about 250miles from my place and i somehow was expecting that my W would make my daughter call up. This morning i tried to dismiss those expectations too. As i said, detachment brings peace into your life that you will need so much.
I have a question for ya, Karma: did you and your wife agree to mutually agree on how to raise your daughter after the separation/divorce? My wife told me when she first annonced the separation that she'd like for us to be able to discuss and agree together on our son's life, etc. I'm just wondering why your wife is holding y'all's daughter from just calling you even on Valentine's Day.
