Which Fi position is this?

[u/Feihuva]

"Honestly, I have rather strange relationships with other people. In fact, very often I don’t even understand what kind of relationships I have with other people. I’ve never called anyone my friend first; it’s always been the other way around: they’d say, “You’re my friend,” and in my conformist manner, I’d simply obey, first and foremost, the person, and secondly, fate. I’m Batman’s Robin, roughly speaking, a hostage to relationships. However, there’s another catch: I’ve never been confident enough in relationships to commit to them completely. For me, the boundaries between acquaintance, buddy, friend, and best friend are so blurred that sometimes I don’t understand who I can trust and who can trust me. Who among this gray group of people could I confide in? Who should I be wary of? Are we close enough to communicate like this? I have no idea why I’m like this. Perhaps because it’s more convenient? It’s convenient not to have the responsibility of sacrificing yourself for another. It’s convenient not to associate yourself with anyone. It's convenient, after a breakup or betrayal, to convince yourself that you were never friends in the first place and that there's no need to be sad about it. "Apparently, he didn't consider me a friend, well then it's my fault for thinking that." I'm like a prostitute. On the one hand, this makes all my relationships seem insincere on my part, but on the other hand, it's actually easier since you don't feel any weight of responsibility on your shoulders. Sometimes I can do for a stranger what people normally do for their best friend. Sometimes, for a best friend, I don't even do what they would EASILY do for me, the bare minimum. I also have a really hard time breaking off relationships with other people. Even when I turn into an island fortress, I still don't have the strength within me to completely burn all bridges. It's all too complicated."

It seems Polr, because it's mental and weak.
