I am not quite sure what he needs 2 weeks for? I don't think he should have any weeks. He can write a letter to the D, and personally, I think he should end it with OB (other b*tch) with you there as well. In person...because you both see her on a daily basis, and you need to have a united front.
He has been lying all this time, I am not sure how you'll be able to trust him. IF this is going to work, he should have his computer in the living room area where you can see it. Nothing hidden. You both should switch jobs - maybe move out of the area. I am glad that you are still planning to see attorney, etc. to get all of your ducks in order. He has shown that he has lied consistently all along.
He needs to prove to you that your marriage is worth it. And I'd get tested for any diseases - he's been f***ing both of you at the same time. You need to think about that - he's had sex with her, told her he loves her, he screwed you out of a good anniversary possibly to be with her. She probably knows a heck of a lot more about you then you'd like. He is obviously adept about going behind your back.
You are going to have to tell him now what you will accept. I sure as hell wouldn't accept two weeks. If its two weeks, it could be 3 weeks, 3 months, etc. He needs to make his decision right now. Maybe a couple of days to pack up anything she's given him to give it back. A note to the D. I'd give that. To delete all emails from his computer. But not more.
I'd personally let him know that you were keeping all of your options open right now - he needs to prove it is over. I am not sure how he can completely do that, since he could always go to the library and such and use the internet there. But you do need to be firm - you have a great backbone now, and you have to do what is right for you.
