Let me get this straight....
You leave without your wife who is stuck in the house all week, to go to town, to go shopping. She comes downstairs in her bathrobe as you and small boy are getting on your bikes ready to go, and asks what's going on. Your response is "You said you didn't want to go"
No. Your wife would NEVER Have said that, considering she's stuck in the house all the time. You then say that you did talk to her, when you got up at ~7 ish this morning. When she was STILL SLEEPING!!!!! It's not valid when SHE talks to YOU while you're sleeping, but it's ok for YOU to do it to HER. WTF? When she says "But I do want to go..." and your response is to close the door in her face with a soft "We'll talk about it later."
You WONDER why she's angry at you for leaving her behind.
You don't have much consideration for her feelings do you?
