Another newcomer - already finding help

[JKL2009]

I screwed up today - I had a password to WAW email account and I forgot to clear my history so she saw I had been in there and looking. On one hand, yes I got evidence of EA with OM, no real smoking gun on PA. But now she knows I know, which means she will not be using an computers at home anymore. Of course she is angry and this will just put fuel on the flames and make her more convinced she can never trust me.

What do I do know? Is it time to contact family/friends and call her out? That just seems like it will completely torch the 1% I have on getting this marriage saved. Should I wait things out and see what happens? I am more and more convinced that she is too far gone.
