I am learning that all this is so true. My W lost respect for me somewhere along the way while she built up a bunch of anger and resentment at the same time. I started to realize how I looked in her eyes as compared to the OM and I didn't measure up even though he is a low-life POS predator, etc etc. In her eyes he was her savior, while I groveled for her love and affection begging her to re-commit to the marriage.
I see every 'newcomer' coming to this site doing the same thing for the most part and I hope that they can gather up the strength ASAP to reverse this behavior. The longer it goes on, the more damage it does I think but it may be recoverable.
