I would keep sending the evidence to her, if she tells you she doesn't care, you can stop, no harm done.
The thing is I don't really have that much left. The one I sent was hard hitting, anyway. If she doesn't buy that, she'll only buy pictures of them kissing or something more obvious. I don't have that.
Her choice.
Sounds like we need a new name for this approach -- "The Big-Bird Approach." (as betrayed wife sticks her big ostrich head in the sand . . . )
When she's ready, she'll be ready. All you can do is what you've done.
