(Vix's husband here)
I'd like to echo the sentiment that I hope she appreciates the 2nd chance you're giving her (as in a super gift). I also think it would be a good idea for her to at least read over this thread if not join the board herself. Many people on the board have experience dealing with broken boundaries and are more likely to be helpful rather than just condemning and judgemental.
One of the resources Wife and I found useful was the book "After the Affair" about how to rebuild after a broken trust issue.
