If everything went down exactly as you described above, I think you're over-reacting.
I don't know if you missed this from my sitch, but he sounds like he is where I was about 2 years ago. I've cut and pasted and bolded a few things differently from my original post:

That's all I heard... problems, problems, problems. Later on she didn't even need to utter a word. A look, an expression on her face, body language, an action... was all that was needed express her disapproval of me. People don't need to scream to communicate. With this constant onslaught I withdrew emotionally and physically. Every time I gave something it was reciprocated with a slap in the face. I reached the point where I had nothing left to give.
My life had been my wife. I felt I had failed her and myself. Her Venus-speak led me to believe I was guilty of everything. At one point I honestly thought she would have been better off without ever meeting me. Not only that, her constant nagging and complaining had killed whatever attraction and love I felt for her. So I left. I needed to figure out what I wanted to do - free from external factors that could influence my decision. One thing that is important to mention here: I was in emotional pain and had no 'resources' (supportive family or friends I could trust) to fall back on.
Don't think I'm discounting your feelings because I know they are real and you're in extreme pain.
Someone asked me what made me wake up... The first two to three weeks I was away she would call me every two days. To tell you the truth, I didn't want to hear from her. I used the excuse of call costs to keep conversations short. During that time she would only ask how the job search was going (and some other stuff, but I don't remember...) All I heard was... She just sees me as a meal ticket.
After three weeks ILY's and "I miss you's" started coming through. The distinct absence of daily 'triggers' (mentioned above) allowed my resentment walls to weaken. I had plenty of free time to truly think with a clear mind. I decided to give it another shot. I gave her a 'trial run' without her knowledge (yeah, I'm a bastard... sorry) She came over and the boundary I put up was: "We're on our second honeymoon. NO COMPLAINTS." She tried but I flagged them down. Without the complaints in the way I was able to "see" her again.
So WTF is my point?
Your mind is playing tricks on you. You've admitted your resentment is building... and building... and building. Mine was too. I was so tightly wound up that I would interpret even the slightest thing as an insult. I would look for reasons that weren't even there to justify an excuse. The sad thing is Luv, BOTH OF YOU are doing this.
BOTH of you need a time-out. Look at his 3 day business trip as a blessing. It's not much but it might make a slight difference. It will give him a little breathing space. (Barring the existence of an affair) And let me tell you something else... At this point in time BOTH of you are susceptible to an affair.
You have three wonderful days of peace of mind my dear. Your mind is messing you up. Take the time to cool off. Your proximity to each other at the moment is detrimental. Your mind is your worst enemy right now, MORE than he is.
