FYI...the advice that you're getting, especially from robx, is good advice. Most guys in these circumstances operate on the basis of fear...fear of pushing her away. Fear is not a good basis to operate on. Reason, and sound logic, and strength...these are a good basis to operate on. And that's the kind of advice that he is giving you...take it. You'll be better off, regardless of how things turn out with your marriage.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
