If you can, try not to snoop, and act as happy as you possibly can, (I know that's hard), but if you think about it a happy smiley face is much more attractive than a sad/ angry one, which will remind your H of what he has done, and make him feel guilty.....which in turn will make him avoid you.
I nearly drove my H away again because of blame and constant nagging thoughts about OW - she was in my head ruining my M even after she was 'finished business' as far as my H was concerned. So if you can, keep things light and fluffy and loving.
