Oh barf! So you get to have OW thrown in your face all the time like I do??!! I am so sorry!!! And sorry for those around you, its like their support is nice, but sometimes pity is hard to swallow!! GROSS to your H carrying on like that. Work is my escape and I can't imagine it being 'tainted' like yours. But then again, a lot of other things are tainted by my OW.
Maybe if you can line up the days and if you said that on the day he was there, you'll be good to go. I erase my history every single day at home. I haven't typed anything here that H couldn't read, but its my outlet, not his.
