Hi Beachblues ~ I'm so sorry she cheated. I'm sure it's hard/impossible to REALLY trust her now. I'm sure you have a lot of doubts.
I think now would be a good time to get some marriage counseling. It sounds like you two don't REALLY know how to communicate. There's almost an "art" to it. Most people don't do it very well. LOL You have to be open and honest to be able to truly communicate, and in a marriage it's vital that you DO.
So ask your wife if she'd be willing to go to marriage counseling. I'm assuming that YOU would be willing, right? I think a therapist would be ideal in helping you two get back on track. You sound like you're very willing to WORK on the marriage -- so if she refuses to go, you'll at least know that she's not as willing as you are to work on the marriage.

Hopefully, she'll agree.
I wish you the very best. Will you let us know what happens please? God bless and please take care. Big hugs, Lee
