Should I break up with him?

My boyfriend’s amazing. We started dating in senior year but I always thought about him through high school. Dating him has been so much different than I thought it would be but also a million times better than what I ever imagined. He’s my first time, the first guy I’ve been in love with, the first guy I’ve been with for over a year.

We are LDR for half of the year because we go to different schools so this is our first summer living in the same town again. Ever since we got back it just feels different. I used to love visiting him at school but here I just feel like I always need space. I get so annoyed with him sometimes - not because he’s doing anything mean or harmful, just because. Like today he was mimicking this baby I take care of and usually it’s funny but today I just told him to stop all annoyed. Or he constantly asks me if I’m having a good day as if my answer has changed. And just compliments me non stop, like every five minutes. He’s such a funny, sweet guy and I hate feeling annoyed but I do. And I think “I should break up with him”. I don’t know what to do. Is this a phase? Will it pass? What if it’s a huge mistake?

UPDATE: We talked about things like some of y’all suggested! Thank you guys so much for giving me a new perspective on things, I feel much better. We’re going to work on it but there’s no pressure, we’re just seeing how things go.
