Guy liked me because I'm alternative looking, proceeds to have a meltdown over me wanting another piercing

I'm into alternative fashion, have a mohawk, piercings, etc...

A guy really liked me, persued me, complimented how unique I look and dress, kept going on about how beautiful and how much he's attracted to me

Until I said I want another piercing or to dye my hair again, which he was against I sent him a picture wearing a fake version of that piercing and he proceeds to have a "panic attack" and meltdown on the phone, saying I gave him pain in his chest fr

Why do men want to date alternative women but meltdown when they wanna keep looking alternative, like they did, when said men approached them.
