Should I break up with him because of his parentage

So I have been with my boyfriend for 4 years. Since day one his parents never liked me. I dealt with it and have been nothing but nice to them. I go out of my way to get them a nice Christmas gift, send texts on other holidays etc. for whatever reason they hate me with their son. I legit visited them and my bf was called into work when we were having dinner so I stayed there since we just started to eat. They legit had a conversation between themselves the entire time as I sat there with them. They are controlling his life and when he can visit me (we are long distance). He’s 25 and pays for everything on his own he was supposed to be moving out to get a new job to a new city and his parents legit made him change his interview for a month later. I hate that he’s in the middle but honestly I can’t deal with his parents they are insane. They think they control his life and he’s stuck. Now it’s affecting me since my bf was going to get a higher paying job and be closer to me and I know it’s his money since we aren’t married but him making $25000 more a year is a huge increase that he could save a lot more for our future (im in grad school now so not working yet). But now I’m not even sure I want to marry him because of his parents. It’s just too much to handle. I know they love him and it’s hard to see him grow up but either they are going to lose him or he’s going to lose me since I’m about done. I don’t want my life planned around his parents. I love him but at the same time want to marry someone who parents love me to. Idk if his parents are just insane because they don’t like me but it’s so hard. And like I have tried so hard to get them to like me, to talk about themselves literally everything. And I don’t mean this in a snobby way but I truly am such a positive influence on my boyfriend, I am very independent am setting myself up for a successful career when I graduate like there’s no reason for them to hate me so much.
