I knew I'd get this response. Absolutely work man and I'm pretty strict about it. Just wanted to be sure what I'm thinking is correct so that I start getting strict with her and we only engage in work related topics
I know it's the sort of thing that's easy to say, but it's 100% true. It's hard enough even to get a girlfriend to keep committing to some productive habit or routine when there's any kind of friction or drama in the relationship, I can only imagine the amount of trouble it would be trying to manage the productivity of a woman who's married to someone else, and whose relationship with you is predicated on the excitement of breaking rules.
There's also the problem of leverage, if she ever wanted to mess things up for you she probably could, even without asserting anything except the truth. And from what I have seen, the greatest lengths a woman will go to in raining destruction on a man is to protect her reputation, which is on the line here.
Personally, I think it's best to keep women and work as separated as possible, unless she's your gf/wife and she's 'helping out'.
