Should I leave my boyfriend? *slight trigger warning*

okay so we've been together for a few months and (no judgement please) we're a dom/sub couple, he wants me to cut my hair into a pixie cut cause he has a "short hair fetish" and I'm not comfortable with it, and I told him no I'm not cutting it, im nowhere near comfortable with it that short! and he said "I'll cut your f___ing hair and choke you with it and spank you with it" and I just said Okay... then he said "I'm your Dom you need to f_ing listen to me and cut your hair" then he said his phone was dying and hung up so me being upset about it I texted this to him "I love being your sub, but I hate feeling like I HAVE to cut my hair the way you want it, I don't like being forced to do something I'm not comfortable with, and you should understand that but it doesn't seem like you do, my past experience with a dom he was abusive and made me change who I was, maybe not physical changes like my hair, clothes etc, but they forced me to become someone who I wasn't, I've finally found the old me again and I don't want to change anything physically or mentally, I hope you understand this so I'm leaving it up to you either take me for me as I am right now, or find another chick who may or may not be even will to touch her hair, I want a dom to love every little flaw, every mistake, and to help build me to be the best sub I can be, and who is willing to work with me through things, if I'm not comfortable and find a middle ground that we both could agree on, so talk to me whenever."I just needed to vent I'm fed up with this.its all he talks about is cutting my hair also sorry for the long post aha.
