Not to be a jerk, but it sounds like you got yourself a marriage of convenience. On both your ends.
Just know that right now she has no reason to change. She will probably keep at it with OM and may even get more obvious. IMHO the only way I see her not bein with OM is if he gets tired of messing around with a married woman. Then again what's to stop her from getting another OM.
I think DB is great, no better way of getting a spouse back than helping them see what a great partner they are losing.
As of now she gets new and improved Jake, and dreamy OM.
You are right Jake, this is your sad reality. The sad reality you choose to accept.
