Praying for your broken heart
.
The only thing we can do with broken hearts that will get them mended in the right way, is to take them to Christ. He cares about your hurt...very much. But before He can help us, we have to turn ourselves over to Him completely. It's like going to a doctor
...we have to tell him all of our symptoms and trust that He knows best and then follow His prescriptions for our healing.
When you say you can't even pray....that is when you really need to. Don't let hurt and resentment turn you away from God....this is EXACTLY what Satan is trying to do to you. I'm not calling your husband 'Satan'....though he can be influenced by the evil one (as we ALL can). Use this as an opportunity to develop a Christ-relationship. People will always let us down, but our Creator never does. He loves us with an everlasting love that even looks past our sins once we accept Christ as our Savior and follow His ways.
Our most painful situations can be stepping stones to heaven...IF we react the right way.
Take your rage to God and get that under His control. Then after prayer and bible reading (especially the gospels...I like to start in Matthew), go to your husband with calmness and try to talk to him about the future of your relationship. Be ready to admit your errors also. None of us are guilt-free when a relationship suffers.
Praying for you both....calmness, forgiveness, love, and open hearts to Christ's leading. Attending Church together can really be helpful. The love and support you get there plus hearing God's Word preached can be very powerful!
