I wish I could link to some of my original threads, but they are gone now. I posted of the utter despair and devastation that I felt, and when I reread some of those threads later on, I felt so sorry for that woman, and couldn't believe that it was me who posted those things as I was bereft.
When your husband leaves so suddenly, it is as if he had died. He is gone, you are without him, yet actually he is still there, he just doesn't want you , so you have the feelings of rejection also as somebody posted earlier.
The last thing you want is to see that person, but if you have children , you have to deal with them in some way. My XH wanted to come into the house, lets be friends! I couldn't see him without crying, so didn't see him at all, not once it was totally clear to me that it was over.
You think you have lost your soul mate, you think you can't last a day without them, but you do. you get through 1 day, then 2 days, then it's1 week, then 1 month, 1 year.... one day you just realise that you are ok and that it doesn't hurt as much any more.
I can talk about it now without crying. That is how I know that I have healed. I despise him. I despise his girlfriend. but she is a serial cheat so I know how their story will end. It used to be all I longed for, but now I know I couldn't give a damn. That is how I know that I have healed.
It is literally a step at a time, day by day. Old cliches, but true.
There is a "script" somewhere, I will try and link it.
