In contrast with many people who've previously commented about how you should "get a new boyfriend" (you don't have to do that over your Quaker not liking him), I think you should sit down and have a chat with him about maybe helping some with your Quaker - changing water, uncovering his cage in the morning, and maybe feeding him millet? I know how non-bird people are, because my dad is like that, but I've talked him into at least feeding my birds millet so they get to know him and his energy y'know?
Please don't dump your boyfriend over your pet not liking him - that's not a good enough reason to separate! There is a way to get your Quaker and your boyfriend like each other, it just might take some pushing to get him to realize that if he wants the squawking and mean behavior to stop, he has to get involved. But emphasize that it doesn't have to be physical contact interaction! It could just be feeding him millet!
(Also if you're worried about your bird injuring another person, it would be your duty as a bird owner to clip the bird's wings (or have them clipped) until the bird is no longer a threat.)
On another note, there was a separate thread wherein people were discussing reasons why they can't have a relationship because of their birds, and I completely disagree with anyone commenting about "I've seen behavior like this before" and "None of my lovers like my birds so I dumped them" and "it's me or the birds" etc. etc. etc.
Relationships with birds who hate your SO are normal and fine (and obviously they happen a lot more than I thought?). It took so long before my first bird Jersey would accept millet from my mother, and I'm about to bring home a GCC and if he doesn't like my boyfriend? I'm not going to break up with him. Simple as that.
It's going to take some time and effort, but maybe there's a way you can coax him into doing simple things that shows the Quaker that your boyfriend isn't a threat. I wish you the best of luck, and if you ever need anything I'm always here to help! (Cause I might be going through the same thing soon.)
