Should I break up with him ? HELP

My bf and I have been together for 4 years , we are generally happy together but we have constant fights about his family . They constantly need things & we constantly have had to cancel dates , vacations , plans Ect bc one of them always needs him for something .

Majority of the time it isnt anything important ...

Example one time he was extremely late to an interview bc his dad was busy yelling at him for not having gone to the car to help his helpless 21 year old sister bring the groceries in ...

He recently cancelled our Valentine’s Day plans because his dad randomly decided he’s gunna redo their kitchen ... and he’s making my bf help him . And guess what NEITHER OF THEM KNOW HOW TO REDO A KITCHEN .

Idk why but this was kind of the last straw

For me . I feel like I’ve been understanding for years now and I’m sick of it . My bf didn’t speak to me for 2 days after the fight .. and we recently finally spoke and I told him that I want to be a priority in his life and that he needs to stop canceling on me for them ...

Guess what he said .. he told me “ Even ig we get married No one is every going to be more important to me than my parents and my sister unless I maybe have a kid “

It literally disappointed me so much bc i understand parents being important but I feel like if we get married I should be the priority ..

I told him i have nothing to say to that and I just feel sick to my stomach . I feel like I wasted 4 years of my life with someone just to have them admit that I’ll never be important ..

Im thinking of breaking up with him but Im uncertain if I’m over reacting or not . Can you guys give me some genuine advice ? Especially if you’re older or youre in a long term relationship as well ..

( Im 23 years old and he’s 24) .
