Affair at the end game

[Awoken]

W and kids are out of town; I'm missing some bills and went into her room to look for them. She's taken others in the past.
The hotel card was on the floor next to her bed in plain sight. It's crossed my mind that she left it out on purpose just to torment me, but most likely she dropped it when she was packing in a hurry.

I went back and looked some more tonight, and found a purse that had receipts and a matchbox form a colorado ski resort, then I found a copy of an email from the OM with the flight info to the ski resort. She was supposed to be going to denver to visit her "aunt".

I'm sure I'm torturing myself at this point.
