There are a lot of posts about fps and it never occurred to me that my uncanny ability to make one person my world could be a symptom. Even when I try not to do it bc I've been told that my old fp needed space and essentially cut me off I still end up making someone my fp. Is this a BPD thing you could explain. Like why do we do this
FPs are definitely a borderline thing, but can be a result of other mental illnesses or just general unhealthiness.
We do this because of different reasons for different people. FPs can result from the borderline lack of object consistency, need to create our own personalities, and black and white borderline thinking.
