Welcome to Hero's Spouse' I am sorry you are having to go through this
His whole personality has changed overnight.
He’s turning his back on his faith he has held dear his whole life.
I realize now those well meaning people probably just pushed him away even more.
I’m heartbroken, he’s been so cruel.
Going through a divorce when none of this is in your control is very painful. Making sure that you are financially protected is essential though. Sometimes we have to separate the business from the emotional part of this.
You have been though a huge shock and it will take some time to get through this. It sounds like you have some family support. You may also want to see a therapist.
Concrete things that help are exercising, especially outdoors, journalling, reading RCR's articles which help to explain what is happening..those who love us often don't get that something changed our spouses. Getting enough sleep, eating well and perhaps finding something that you enjoy doing will all help you.
I don't think that well meaning people have pushed him further away. This is what he feels he needs to do and it won't matter a bit what family and freinds say...he will do what he feels he must do.
If you too find your faith helpful there are a couple of good resources:
Brokenheart on Hold by Linda Rooks
Lysa Terkeurst's devotionals and book "It's not supposed to be this way"
Rejoice Ministries Charlyene Cares daily devotionals.
This is his crisis and really has to do with something internal in him...it isn't about you or your marriage but it does affect you.
Detaching is not easy and you have children involved. It sounds like he contacts you...we label these as "clinging boomerangers" and it's ok to have contact with him as long as you can deal with it. It can also give you some insight into what is going on in him. But it isn't easy so some people feel it best to cut all contact with them. That is totally your decision and can change from one day to the next.
Ask questions and others will be by to give you some support.
Where do I go from here?
You start a journey of your own, finding who you are without him and who you wish to be. It isn't easy and you need a great deal of patience with yourself but you will get there.
