Is it normal to love your parents but reject them?

I love both my parents but I grew up very differently from them which I think is the main reason we don't understand each other. They do many things in a controlling manner and have never really agreed with my personal choices. They sacrificed their lives for me so I can't just tell them to fuck off, nor do I want to. Because of this I can't even remember the last time we had a real conversation because I know they don't agree with what I do or how I do it and they like to ask questions they know I don't want to answer. I also can't remember the last time I said I love you to them because I just don't know how. The biggest thing is I feel like I resent them now and even simple small talk gets us both irritated and going at each others throats. Is it normal to have love for your parents and at the same time reject them in a way?
