"What do you guys think?"  I think you need to go into the marriage counseling with an open mind.

I am sure this was very hard for you as well as for her.  I am glad she agreed to see a marriage counselor with you...otherwise, you both might never have gotten closure...or might have always wondered "what if"...or might not have gotten a second chance...who knows what the future will hold!  Good luck to both of you...together or apart!
