Jennifer, I am so sorry that you are going through this.
I am not an expert and I dont know your h but he sound like he is still going through his crisis.
Hard as it is going to be right now, it is very important that you take care of yourself and your kids.
Your h is going to have to find his way.
And you are going to have to find your strength.
You have to follow your own path to peace. That begins with realizing that you need he has to walk this journey in his own way and you need to let him.
So, have a good cry. Then, remember that you will get through this.
Focus on you and your children. Take it one step at a time.
