I’ve been trying to figure out if this is a ‘me’ thing or a bpd thing but I am also new to reddit so bear with me. 

If someone hurts me a great amount I will lose all respect for them and cut them off/hurt them without caring at all. I’ve done this with friends and family but it’s the most noticeable in romantic relationships. I was seeing this guy and we weren’t seeing anyone else, everyone knew we were together but we weren’t official because he was scared of titles, said he needed to focus on work (he’s a narcissist that’s another story altogether you get the point) and this really ate away at me and so I was waiting for him for basically a year until something just snapped in me and I didn’t want to be with him anymore. I kept distancing myself, trying to leave him, he even cried for the first time in years, but I didn’t care AT ALL. Is this splitting??? or am I just a terrible person/have a whole different problem?
