Oh, stop. You are tired, you are stressed, you are not living in your home, and your marriage is up in the air. Your emotions are going to be all over the board regardless of how your wife talks or even looks at you.
Chalk it up to a bad day and move on. Today may be better. If she sends you more corporate emails and gives you more business talk... she's trying to keep herself composed and emotionally distant from you. Try not to read too much into it, like Cathy said.
I'm headed out of town and I'll be back tomorrow. Keep your chin up. Hope you could get to the MP3. Lemme no.
