I'm another Chitown Burbs guy too. Youre sitch is so eerily similar to mine that I had to make sure I didn't actually write it.
I cant write much right now since I'm typing on a phone while out in Vegas for the weekend. But try to stay strong. This has been the hardest time of my life so far. But I'm still trying to focus and stay positive, and trying hard to not backslide.
But after a couple days in Vegas so far and seeing how the other guys are "having fun (and I don't mean gambling fun), I know I truly still love my wife cause I find that I still can't get myself to want to have any part of that kind of "fun". She'll probably never actually even know how much I do love her even when 'tested' this weekend cause the bachelor party trip will never be spoken about outside the group of guys. w
