I dont know that I would focus on being her perfect H, instead focus on making yourself the best H that you can be, be the kind of spouse that ANYONE would be nuts to leave. Considerate, wise, compassionate, strong, committed. One of the first things that is talked about in the books is re-establishing your friendship. She wont remember your connection while she is connecting with someone else, and hes not going to vanish. Take this time to work on you, theres not much else you can do right now. And it might just make her see a side of you that she hasnt seen in a while. They had the books at my local library, I still bought them, but it was nice to have them immediately. I really think that you should get them.
Investing time and energy in improving yourself is always worth it.
I guess I gave the wrong finger to the wrong man...
