Thank you for believing in me. Your story/advice is incredibly encouraging.
This afternoon, I suspended my W cellphone service. I came home early from work and calmly told her what I decided to do and why (boundaries). She became very angry, accusing me of being controlling, manipulative, etc. She said she hates me and wishes we never married. I remained calm throughout. She Said that it was "our" money and stated that I couldn't do what I did. My reply... "It's family money to be used for our family needs, not for you to blatantly disrespect all of us by having an affair".
I'll post more about our conversation a little later. She talked about leaving, taking the kids, not having any money of her own, etc.
