I told him “what if I can’t forgive” his response “let me know” ?? i was like really???
He doesn’t deserve to have you forgive him. He can hope for it, but it is pure mercy if you do. If you don’t forgive him, or if his repentance and purpose of amendment are not real, your marriage is over, and it will be his fault. Even if the bond remains, if you cannot forgive or if he does not repent, you won’t have a common conjugal life in any true sense of the word.
Perhaps he means this: He does deserve to know if you realize that you can’t or that you won’t forgive him, and also if you hope you can forgive him but know that you cannot put him back into a marital position of trust (which are different things). In either case, any reconciliation between you will not be a reconciliation that saves your marriage. It will be a reconciliation that keeps your separation civilized.
By that same token, you deserve to ask him this: Is it your intention to repent of this infidelity, to take steps to make sure it doesn’t ever happen again and to make amends as necessary to rebuild my trust and our marriage? If he doesn’t, then I think you have your answer about whether or not a reconciliation is possible.
My advice is to find your pastor and make a plan to get both pastoral and professional support to work through your feelings about this. You need to give yourself time to digest this and you are going to need guidance to help you learn your own heart and your own mind. Marriage counseling can follow after you have got your emotional “sea legs” concerning your own feelings.
If you can find the book, “How to Forgive: A Step-By-Step Guide” by John Monbourquette, I’d highly recommend it. It was written by a priest and psychiatrist. I didn’t find every bit of it helpful, but his description of the process of forgiveness and (where it is possible) reconciliation was very helpful. He also highlights “blind alleys” that don’t work, which is helpful. It is highly likely that your library does
not have it, but I think you can get it on Amazon.
