Simple. Talk to him, ask him why he did this? Share with him your hurt, above all, forgive him. It's the crux of your faith -
And forgive us our debts, as we also have forgiven our debtors. Matthew 6:12 NIV
“Then the master called the servant in. ‘You wicked servant,’ he said, ‘I canceled all that debt of yours because you begged me to. Shouldn’t you have had mercy on your fellow servant just as I had on you?’ In anger his master handed him over to the jailers to be tortured, until he should pay back all he owed. “This is how my heavenly Father will treat each of you unless you forgive your brother or sister from your heart.” Matthew 18:32-35 NIV.
What he did was crasss, a betrayal and a compromise of your trust. I get that. But compare that to your sins against God and His total forgiveness, how can you compare that with your sin, complacency and disregard of God and Jesus during your life? Please please, don't be a wicked servant but instead really forgive from your heart, FORGIVE and forget.
Enjoy intimate moments with your husband, that's total forgiveness. Move on.
God bless you darling, lovely sister. May the Lord bless your union by being a 3 way union; you, your hubby and Jesus, in an intimate bond, all 3 of you together in a shared love along the lines described by Paul in Ephesians 5:21:23. Prayer, Bible study, praise, reflections and discussions. Together, draw close to Him and I'm sure you'll grow closer and more intimate with each other.
God bless you sis, love xx Andy
