I'm currently looking at quiet BPD and stuff with my therapist etc and I was wondering about this 

Is it splitting to go from really liking someone to indifferent to them? Because when I'm in a romantic relationship and someone does something that makes me feel like they don't like me anymore, I don't really get outwardly mad (unless they instigate it) but I cut them off completely and forget about them really fast. And I feel like when I stop idolising people I don't act out and just cut them off bc there's nothing I like about them anymore so I'm bored 

When it's a platonic thing I think I get angry at people rather than detached, but I've only really seen professionals talk about the anger

I can't find much on splitting online that really makes sense so I was wondering if anyone could relate
