She's not on-board with the changes that are happening within you and this is normal. Be intrepid, even if she snaps at you. My wife acted like I was trying to beat her up when I would stroke her hair and ask for kisses. I was a bit too forceful and she was dramatic as hell. Eventually we found some kind of balance. Keep telling her how pretty she is, etc. No matter the intellect, all people want to feel wanted. I still bug my wife about sex. She still sometimes acts like she's doing me a favor. I do it for me, but our relationship is so much better when we "make love." Oh, and don't take what she's says personally. It can be very hard not to get angry, or feel diminished, but your wife is just getting used to the new you.
