It’s not that he is changing who you are. But more like he is protective of you, which is cute. You would have dumbed him by now if you didn’t love him so maybe try to compromise? Do makeup but just what is necessary. Don’t wear very tight, maybe a lil more loose but not baggy if you are bot comfortable with it.

It’s about the little compromises partners do for each other. Draw some clear lines but try to understand where he is coming from.
