You should put a plan together of how to repair this...
Put a list of things for HIM to do at work to earn back your trust and YOU put a list of things together to help him believe the marriage won't be like it was when the affair started.
The lists should look equal in size and effort. If the hosue was messy and he didn't like that before the affair then you make a point in your list to ensure the house is tidy etc...
You can start to draft a plan on your own and share it with him later on... Just make sure you both have a lot of work items there... Or fights will start up...
I Do think there's more he can do at work to minimize contact... There are couples who have changed jobs and moved away to repair the damage made by the affair.. All your Husband appears willing to do is to move his desk further away?
Sorry, I am not swooning by that at all...
You have to look at this like dating... You feel violated by this woman and the best he can do is move his desk? That sounds like Mr Right to me! [scarcasm]
You can start journalling the list here if you want... you should get a lot of input on that...
