Can’t tell if my [20f] bf [21m] loves me

Can’t tell if my bf Ioves me or not

He’s so nice to others, but gets so mean to me. Can’t explain it without sounding crazy, but the way his tone gets annoyed and angry when he’s teaching me to drive and I make a mistake, when I’m in a way of someone, when I can’t hear him. Told him it hurt me, He got mad saying I’m blaming him for everything, told me I should just listen. After a lot of back and forth said if don’t change he wants to break up.
So I tested this, didn’t react to anything he did and just followed his directions. he seemed really pleased towards the end, like that’s how it should be.
His 7 year old Sister gets similar treatment. he hit her too hard while play fighting teaching her self defence. she cried, he kissed her while apologising then said “u asked for this”. Outside of these situations, he’s caring towards her, plays with her alot and protective of her safety.

He admitted he only ever argues with me, his mom, and his sister. He never argues with his friends, but complains to be me about them, also said he argued a lot with his ex girlfriend too.
He gets angry easily in general but doesn’t show it to others.
It’s so confusing cause he does all those acts of care, asks for my opinion on things when making his decisions like he genually needs it. He says he cares for me the most but feels like I’m first to be sacrificed when something goes wrong.

I was drawn to his calm and gentle nature. Confident, but soft and quiet.
Starting to think, Ironically maybe that calmness might be the very thing that ruined me.

Honest observation, he is very sensitive. Doesn’t wanna hear anything stressful, response to ever problem he is visibly worried about “don’t wanna think about it”

Maybe his calmness doesn’t come from inner peace and acceptance, but from avoidance. Maybe he avoids things that are heavy, avoids having to face hurt, fear, form conclusions, and change.

Maybe his “calmness and gentleness” still existed when I was hurt , but it came at my expense, I was just another thing he wanted to drown out. He used that word a lot.
I made so many scenarios but idk, maybe it’s as simple as he just doesn’t love me lol

Going out 5 months, relationship 5 months, I’m 20 he’s 21.
