I have been through what you are going through, and i know it is not an easy place.
My personal advice to overcome it is by abiding more in your first love, and that is our Lord. Once you shift your focus to the Lord, He will start healing the hurt you have experienced, shall start removing those roots of bitterness that are taking hold in you. So start being genuinely thankful for everything, including your husband. Love conquers all, it is the ultimate antidote for pretty much everything.
Then start sowing seeds of truth. God’s Word shall not return to Him void. His Word will sprout and take root eventually, where it has been sown.
Avoid any condemnation and judgement toward him, only God can judge and convict him of all he’s doing. And that peace that surpasses all understanding will start dwelling in you.
And as you pray for God to put a hedge of thorns around your husband, and continue to dwell in God, meditate in His word, He shall work everything together for good eventually, according to His will.
I will stand with you in prayer too. God bless you and your marriage.
Philippians 4:6-7Amplified Bible (AMP)
Do not be anxious or worried about anything, but in everything [every circumstance and situation] by prayer and petition with thanksgiving, continue to make your [specific] requests known to God. And the peace of God [that peace which reassures the heart, that peace] which transcends all understanding, [that peace which] stands guard over your hearts and your minds in Christ Jesus [is yours].
