<human>: F, 20 dating M 20, for 2 years. This is more of a question than a real hot button issue, so the first one to suggest a breakup gets karate chopped in the face!

I have recently been wanting to cut my just-below-chin length hair into a pixie cut (aka: really really short). I was all systems go, until I mentioned it to my S.O. 

When I showed him the [pic] of what I was thinking of, he let out an audible groan. 

He keeps reiterating that even though he wouldn't stop me from doing it if I really wanted to, it wouldn't be something that he would like. 

So, the question is, should I respect his opinion and not cut my hair any shorter- or is it unreasonable for him to have input concerning matters of my appearance?

On the one hand, it kind of bugs me that he would actually dislike the haircut on me if I got it. On the other hand, I guess I think that if he's the only one I'm really trying to impress, why would I do something he explicitly said he wouldn't like the look of?

Can you give me the gist of the text in a nutshell?
<bot>: I want a pixie cut, but my boyfriend has expressed concern that he wouldn't like that length. Do I owe it to him to stick to a look he likes?
