Last79, how old is your wife? How long have you two been together and married? (I'd put this stuff in your signature. Go to My Stuff -> Edit Profile. It helps people remember each other's situations).
How was your marriage before things appeared to go wrong? Was she unhappy with you or the marriage for a while? Did she have serious complaints about you? Also, did you wife have a career before you guys had kids?
