Having been through a similar situation of an unfaithful husband, we too divorced. I too have remarried and have struggled with trust, but without trust, there is no relationship. You have to remember, your current husband is NOT you ex. They are two different people and if you believe God brought you together, then trust he will guard and protect your marriage. Try, and I know this is hard, try not to live in the past. It cannot be undone, nor is it your future. Lean not on your own understanding, but trust in the Lord with all your heart! God is good, faithful, and just. The wrongs will be avenged, and all things done in secret are brought to light. I will pray for peace and reconcilation for you.
