I, too, got to hear all about how the OW was everything I was not. I got to hear, "Sorry, you're just not her" during our supposed R. I got to hear him call her name out in his sleep, or tell me he loves me but get the name wrong.
Even got phone calls from the OW telling me I ought to be grateful to her for "lick-starting his sex drive".
Needless to say, it's not good for the ego. My self-esteem went lower than sewage in a sinkhole.
But once my WH moved in with this paragon of femininity, the shine came off the fantasy and he found out that she, the angel who was rescuing his dark and troubled soul, his twin flame, his soulmate, was even more messed-up and clingy than I was. She became the bane of his existence VERY quickly, and within two months he was begging me for another chance.
And I got to see this happen. I had proof that he found out he made a whopper of a mistake. I got to have him sitting on my couch with snot running out of his nose, crying about what a disaster he'd made of our marriage and his own life.
The vindication I felt at this point unfortunately didn't translate to courage, and I took him back.
A year later, he did it again, and this time I let him go without reservation... because I knew what was coming.
Nothing will ever truly take away the pain of hearing your spouse tell you you're not good enough. But slowly that pain translates to knowledge. Knowledge that they made decisions based not on reality, but on fantasy. Not on true love and affection, but on the illusions that they craft in their heads to justify their addiction to the "high".
It took years to get to the point where I no longer see myself through the negative filter my ex slapped over my eyes.
And those were very hard, very painful years.
I don't know that I ever would have forgiven him, honestly, but I can say with no uncertainty that I have learned to look at myself as WHO I AM, not who I am to him.
And I kinda like who I am. A lot. Who I am is a pretty awesome woman.
You can do the same for yourself - engage in things that make you feel good about yourself, and worry less about what anyone else (yes, even your WS) thinks of you. Once you begin to feel that inner confidence again, it will shine out of you like a light and your WS will see it too.
Any recovering CoD can tell you the dangers of taking your own self-worth from someone else's opinion of you. Yes, you want a spouse to cherish you. But right now, the most important part of your healing is honestly to cherish yourself.
Take pride in your ability to love. Take pride in your compassion and dedication, that you're willing to work on this with your spouse. Take pride in taking the right road, and in doing your best, and in going to bed at night knowing your day was spent making life just a little better.
You will have off days and bad days. But do it anyway. And eventually, you will reach that point where you are #1 in your own eyes, and those who demand the respect and adoration of others are amazingly successful at getting it simply by dint of having it within.
