When I was in college I'd find some pretty warped people and play therapist, partially to fed my ego and partially because I thought I could help. I was usually totally over my head and nothing I could really do anything about. I wouldn't necessarily say I sought them out, but after a few years I did begin to wonder why half of my friends I was nursemaid to. I remember one of my old suite mates told me once "you're like my mama bear." That comment really disgusted me and I still don't know completely why. Well I do sort of know why in retrospect because I felt matronly and old and parental and I was barely 21. And like I said it fed my ego because I felt like I was really getting into someone and I liked people heeding my words so carefully and asking me what I thought they should do like I was an oracle or something. There was a little powertripping involved in it.
I'm not saying I'm far past that point, but I've definitely chilled with making myself so available for therapy with people and finding people that I have more reciprocity with. It is nice to have people see that in you though. When my coworker I was having problems with last year came up to me when she was about to have her baby and started sharing her anxieties and fears about the impending birth of her baby I did feel flattered. That was completely out of character of her (she's an ESTP who's always blustering and grandstanding everywhere), but then again she did have hormones coursing through her body so I don't know how seriously to take it.
I'm trying to get some evidence for some thoughts I have about FJ/FJ relationships (platonic or otherwise) because I'm trying to figure out if what people refer to needy/clingy/dependent are "normal" FJ personality traits of if it's something more.
