Jac,
You both need to go to marriage counseling immedidately to see if you can work out your differences. It sounds like there is total lack of communication here.
Counseling is to try improve your siyuation - its not a bad thing.
Office romance is a tricky thing. I've seen many times where some is attracted to some one and the other person is not at all - it makes a sticky situation. Usually they go very bad.
You need to communicate with your wife - you both should go some where quitet - bedroom? Lie and talk - talk about what is REALLY on your minds. I beat $1 million she is holding back a ton!! A ton of things that you do that annoy her to no end - things you don't think about.
