For me personally, it doesn't matter whether you're a friend, a family member, girl, perhaps my future child (if I have one) – if I feel hurt by something they said or did in any way whether they intentionally meant to hurt me or not, its done, my love for them does not exist anymore and is instead replaced by seething anger/hatred ,and then after a while….. nothing I don't feel anything for you.
I don't know what kind of mental illness this is ,but rn im 100% of the time completely numb and don't love literally anybody (maybe deeply I do but idk). It sucks because say in a future relationship everything could go perfectly ,but all it takes is one thing that hurt me and it's already over- that could potentially leave me in a great state of pain.
