Yes, it's normal. It takes time to forgive, heal, and trust again.
Why is it so difficult to give your WS credit for the work they are doing to repair the damage they have done? I want to acknowledge his efforts and all of the things he has done to show remorse, guilt, shame and sorrow and I do this from time to time as I believe he does need to hear it. However, when something comes up in discussion and he asks me if he's done anything since to make me believe he is anything less than committed, well, I find it very difficult to say "I believe you". When he asks if I think we will make it, even though I believe we will, I hesitate before saying yes or depending on my mood I'll say "I hope so". It's as though I want to give him a little, but not too much. At least not just yet. Is this normal?
But don't confuse the normal experience with healing change. The fact that you "want to acknowledge his efforts and all the things he has done..." is a good thing! Pay attention to that longing because it will lead you toward empathy and encouragement. And your right: he does need those things from you. He may not deserve it, but renewing a marriage requires grace, not justice.
Even if you have a hard time acting that way now, at least be vulnerable enough to tell your husband that you know that's what he wants and that you want to give them to him. He will be encouraged to know that you want those things rather than wondering if things will ever change.
This is why affair healing is a joint project. The unfaithful spouse cannot do it on their own. They have tremendous responsibility to comfort and rebuild trust, but there are things that can only be done by the betrayed spouse. It's hard work for both, but it's worth it.
Get help if you need it.
