I'm not sure how this will apply to you but hear me out.
I've found that people approach relations generally in one of two ways.
Consistently Instable: These types of people appear instable (maybe wrong word) in the sense that they're quite predictably unpredictable and so relations with them take longer to establish. They prefer to make friends slowly, don't like being relied on by others, change plans last minute, hardly ever plan things ahead of time. Despite these characteristics these people non-the-less care about the friendships they already have and even if they only see a friend once a week they're comfortable with that and are able to keep their friends for a long time. They rarely get into heated arguments with their friends as they prefer to keep melodrama out of their personal lives. (I'm definitely this one, I'm instable in the short term but because I'm consistently instable it gives my personality stablity in the long-term in a weird kind of way, also most my friends would be in this category as well)
Inconsistently Stable: These types of people appear stable, in the short-term at least. They're the kind of people that make friends and then hang out with the same friends every day. They like being relied on and like to rely on others, like to make plans with others (i.e. going on vacation together). Despite the apparent stability, however, familiarity often breeds contempt and these individuals are thus prone to eventually getting into conflict in their relations. They "break-up" with friends/partners badly and suddenly, in such situations drama insues (i.e. they will refuse to talk to each other for months and months after having a heated argument). After 'breaking-up' with friends they are seem to quickly find others to fill their social void and thus their new relations exhibit the same intensity. Because they become so reliant on a few individuals in such a short span of time their personalities are in the long-term seemingly more instable, as they may completely change who they are due to the influence of others.
(These are the kinds of people that appear to 'disappear' for example, when they get into a relationship)
Hopefully those descriptions made sense, I'm not sure this has anything to do with type. I was inspired to write about this by the thread on "drama". Inconsistently stable people are definitely more prone to melodrama so to speak, I notice that certain people almost seem to crave this "drama" in their relations. Personally I find it repulsive, I'm uncomfortable with getting to know someone too quickly and notice that I prefer to keep my relations to others separate (I hang out with my friends on an individual basis rather than with all of them together in a group)
And of course some people can do a little of both, however in relations with other individuals even someone that can do both will tend more towards one than the other. Anyways I'm curious to hear others input, wondering if this can be type-a-fied
