Hey Purr, I am sorry. I am sorry you feel so much pain. Just reading your post made my stomach upset, I can feel your disappointment and pain. I am sorry.
All I can say to you, is to try to focus on what matters, the end result is the same, your wife has chosen to end your marriage and moved on. Being lied to and disrespected by the ones we love is a terrible blow. Finding out your love had blinded you is also a terrible blow. But it is natural. Most of us here did the same. And maybe you found out at the right time to make a fresh start... Stay strong, K
