relationship advice

Me and my bf have been dating for almost 4 years. He is an amazing human beings. I feel like he is the bf that everyone wishes to have like he genuinely loves you and is always there for you. So the thing is that I’ve been wanting to break up with him for a while . The reason is that he puts soo much pressure on our relationship and on himself for our relationship and i hate that and im not happy in our relationship either and i feel like im the happiest these days when im by myself and our relationship has become a burden for me . He is genuinely such a nice person and i feel like an evil bitch for wanting to break up with him . We are a very young couple im about to turn 20 , i feel like you should be enjoying these years of your life rather than putting too much pressure on yourself and worrying about the future and also my plans for my future is different from his.He is genuinely an amazing human but i don’t think so he’s the human meant for me .

I would love to know ur take on this. Should I break up or should I stay?
