I'm sorry about your situation. My wife is in an EA and I think dealing with an EA may possibly be a lot more difficult than a PA because it's so easy to dismiss as "just friends."
I'm glad you're not okay with your wife's EA. You shouldn't be okay with it; it's a violation of your marriage. My wife tried to paint me as the bad guy, and I actually questioned myself a number of times. It took a good MC to whack me over the head and wake me up.
I know this doesn't help you feel better right now, but I know what my MC would say to me if I were in your situation, "Yes, an hour extra at work is a long time."
I know how painful all of this stuff is for you; I'm living it. Do whatever you can to get your mind off of it. GAL, get some exercise and focus on happy stuff. Again I'm sorry about what's going on in your life right now; I hope you feel better soon.
