Stop telling me you like my appearance when I __________.

      Stop telling me, "You look better when you're ___________ (this way, that way, some other way).

     What you should've said is, "I like your appearance better when you're ________."

     Maybe you should have said, "I wish you would suit my preference __________."

     Look!  I'm glad you liked my appearance when I was bald, when I had black hair, when I had a beard, when I had long hair, etc, but 

• There's no guarantee that if I were to change my appearance to fit what you (or anyone else) like/s that we would end up living happily ever after together. 
• Life is too short for me to not enjoy my own body, my own hair, my own choices of clothing as I go all along the way.
• If you really like me, then you like me no matter what I wear, no matter how I wear my hair, no matter what I do.  You like me, because you like me as I am.  Period.
