You are most definitely not alone and made perfect sense. Yes, others feel left out even though it doesn't hold merit.
I suggest that you back away a bit and get on with other things in your life. There is such a thing as being overly involved I think you need to give your wife some privacy. I love that you are so in tune with her. I should think that would mean that you trust her and can let her go about having you to support her while she explores this other man.
Have a good look around on these forums. There is lots to read that is similar. I am sure you will find some interesting similar situations that will help.
