WIBTAH for divorcing my wife because she cheated at her bachelorette party?

Title sums the situation up pretty much. I and my wife are both 35 and married for 8 years. Happy relationship, happy life, stable finances, a good house and both working. However, this changed for me last year when I learned she cheated on me at her bachelorette party with a dancer(stripper?). I learned it because I found some questionable videos on our old drive. She did not deny it or dismissed it. On the contrary, she was extremely apologetic and told me she'll do her best to make it up to me.

I have no reason to think she cheated on me after that instance but my trust is so broken that I cannot build it again. We are on marriage counseling for 7 months now and I do not think it's working. I cannot see the relationship in the same light. I know we had a great life, we were planning to conceive this year and everything is stable but I cannot change my emotions. I started considering divorce for real and lost on what to do.

WIBTAH if I divorced my wife for that reason?
