My wife has known about most every aspect of what I do since shortly after we met. She approves, although she will occasionally ask questions and ask me if I'm sure what I am doing is going to be okay. Not being bitchy in any way, just honest concern. I've felt so good by not having to hide my use from her, but then I've had previous gf's that I would not have told anything about it. You have to decide how important she is to you, and how trustworthy she is with the info.
