of course! bpd is an attachment or relationship based personality disorder, meaning it usually shows itself in situations surrounding other people. lots of people may know the term "fp" or "favorite person", which is an informal term coined to describe the attachment to one or more people in a borderline context. bpd pals often times will experience a pull or attachment to another person because of trauma reason. usually this person is nice, understanding, or chats to them frequently. an fp can be a positive or negative attraction however, and plenty of people will develop an attachment to someone they don't really like all that much. it's normal. having a bpd attachment is usually negative in the grand scheme of things. you may shut out others, blow off work/school, stop eating or other bodily functions like using the restroom, participate in self harming activities, etc, over your fp. there is a extreme commitment to a bpd attachment. it is similar to idolization. there is usually an ideal or correct version of this person in your mind, and people with bpd may get violently upset if this person steps out of the rules that they don't know about. an fp is usually what your world revolves around as someone with bpd, and if they show disinterest you may begin to break down or do bad things in order to receive attention again. i'm honestly not the best at explaining all this in a general sense, but if you have any more questions i will gladly answer.
