Sweetie, this is still so new to you so, of course you are trying to understand it all.
Here's the thing. The crisis they are in is something we cannot understand. And trying to will make you crazy.
So, it is best not to try too much to make sense of it.
The best thing for you to do is to put your marriage safely in a box for now.
Look within to figure out what things about you that you feel need changing. Not the things he is throwing out you, but, the real things YOU want to change.
Then think about the person you want to become. Think about things you have always wanted to try, places you have always wanted to go, classes you might want to take.
GM, I know that your natural instinct is to want to hold on and have contact in anyway you can. But it really is not good for you.
This is a journey he needs to take on his own. And it is best if you just get out of the way of it.
Your part right now is to become the best you. Be the person you were meant to be.
You want him to see a different you. A woman of strength and pride and dignity.
Remember though, the changes have to be real.
So, no more calling him. You're too busy getting a life and helping your children navigate through this, right?
