As long as what she wants is within reason, that should work pretty well. I once had a partner who wanted me to sleep with her crazy sister (!) as well as with various other women I wasn't attracted to in the least, and she also wanted me to get drunk with her on regular occasions and basically act completely unlike my own natural self. Her whole project was to manage me, change me, and turn me into someone rather like Shane McBride. ;-)

I declined on all counts.
