Yep he definitely feels you are slipping away. For the gym thing, he's worried about you looking good for other men.
IMO, I would keep looking and smelling my best when you are around him, maybe even a little naughty looking. Maybe change your hair and wardrobe style.
When he gets upset about things like the driving home issue, just shrug it off as if what he says is no big deal.
The most important thing to realize is that you are the one in the driver's seat now. I used the analogy of the scene at the end of Grease where Sandy changed into the "bad girl" and didn't really care what Danny thought. You are in that position now. You can get him to WANT you.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
