Finding their "love journal" in the trunk of H's car (they used it to write their "love story" to each other). Gross.

Finding movie tickets in the laundry to a movie I didn't go to (after we'd been slowly making progress on recovery and just returned from family vacation). The conversation went like this:

Me: What did you do Sunday?
H: Nothing, ran errands.
Me: Hmmm... didn't go to a movie?
H: Uhhh... oh yeah, I did.
Me: Who did you go with?
H: Who do you think I went with?
Me: OW.
H: Why do you think that?
Me: Because you're giving no reason to think otherwise.
H: Oh yeah... I did.
Me: Click (me hanging up phone)
