MLC, affair, internet pictures, we're a mess

So cleaning up my desk and found a receipt under a pair of gloves that show she and him had dinner last month. Is the divorce busting response to this to just throw it away and move on? I mean I know she is "seeing him as a friend" still.

I feel like confronting her about this will just put us in that same argument loop where she will say her relationship with HIM is not why or marriage is broken (which I agree, but I still say there is no fixing the marriage of two people with three people being involved). Since that is my instinct, I feel it must be the wrong choice.

I also thought about just leaving it on the desk that is clean. She'd see I've seen it. I think that may be passive aggressive though.

I feel like the communication we have had has been positive and I want to build on that. Should I just throw it away and move on? I feel like that'd be fairly detached (letting go of "the evidence").
