Anyone else feel annoyed by the people they date?

I can date someone for a month or two but after a while I get to the point where absolutely everything they do annoys me. It’s almost like a switch flips. Does this happen to anyone else? Is there something wrong with me? I’ve only been able to be in a relationship long term twice in my life. Once when I was really young (high school) and once in my adult life. (He ended things with me, I am single now)
