i know this was posted a while ago but im gonna reply anyway.
so the fact that youre questioning it answers that youre not a bad person.
i personally have bpd and a big part of it is the intense interpersonal/ unstable relationships. when i love someone sometimes i hate that i love them especially when i can point out that my love for them causes me mental anguish. it almost tricks my brain into thinking that i hate them. theyre so good for me that theyre bad. i often let out my frustrations and anger on them and soon after absolutely pour my heart out in profuse apologies.
you should listen to IFHY by Tyler The Creator
(not to say that you have bpd. you can have struggles with intense unstable relationships without having a personality disorder) basically im saying its normal and its good that you are aware of the way that your feeling.
