A feeling that comes to fruition after being involved in a relationship that holds you up or mistreats you in one way or another.
Be it toxic behavior, mismatching personalities, or for another example, someone might say "I love you but fuck you" if they feel deeply attached to their partner but are frustrated by a repeating pattern of broken promises or actions that hurt the relationship.
Man, I don't even know what I want anymore. I just want her to be happy.
Sometimes, I just wanna say .. "I Love You but Fuck You".
