My boyfriend (25M) has grown distant after I (25F) got a pixie cut

My boyfriend and I have been together for 8 months. Everything was great, and he was always very complimentary and loving until I got a pixie cut.<br><br>I used to have long hair, and after having our first huge argument, I shaved my head. I don't know why it upset him so much, and he keeps telling me that he likes my hair, but he also says I look completely different, and he isn't used to seeing me this way.<br><br>Well, it has been 3 months, and he has grown distant from me. He still denies that he doesn't like my haircut and that there is something else going on, but he won't tell me what it is.<br><br>I asked if he broke up with me, would he be okay with me dating, and he said maybe.<br><br>Is this a red flag?<br><br>Please help.<br><br>TL;DR My boyfriend is being distant after I got a pixie cut, and he is being mysterious
