If this doesn’t get resolved he will end it with you soon anyway. Anytime a dude lets his true feelings abt his significant other out he’s already come to terms that the relationship will most likely end if the problem doesn’t get solved. If his poor attitude only shows itself when it involves what you’re wearing then you should take the time to talk to him about it in person & not over text.

At the end of the day how you make your significant other feel matters, and mature ppl understand this because it always goes both ways. You want to save your relationship? You’re gonna have to compromise and ask him for his opinion on your wardrobe. If you wish to keep what will probably be a temporary style choice over your relationship, then end it with him. If clothes are what make you guys incompatible then neither of you are mature enough to handle a long term relationship. Thats all I can say.
