It's more a kind of feeling that you never know who this person is because they never show you...because they can't stand the idea that someone might not like them. Even if they don't like the person themselves! It feels like a lack of gumption and far, far too much investment in what other people think. It leaves you not knowing if they genuinely like you or not, and realising that it wouldn't make a difference either way. I just can't warm to those people because, like I said...I don't know who they are!
This point by @ShebaShimmyShake is exactly right, and it appears to be something a lot of women don't understand, judging by all the posts on here that essentially run 'I do everything for my friends and they never do anything for me'.
These women are not actually being generous, they just never say no to even the most outrageous requests because they're terrified of being disliked -- and in their disordered world, saying 'no' to any request gives other people a legitimate reason to dislike them.
And because their entire method of relating to others involves trying to avoid being disliked (even by people they don't themselves like or respect), they become invisible service-providers to the people they know.
No one really knows them, because their social persona is being whatever they think the other person wants - a shoulder to cry on, a runner of errands, a provider of free childcare, a lender of money, an agree-er.
Again, I've spent my entire life watching the consequences of this in my mother. She has spent her life believing herself to be a generous friend, trotting about after other people, and she's unconsciously deeply resentful that she has no friends at all in her seventies, and is completely baffled and resentful that her daughter (who often says 'No, that doesn't work for me' or 'I don't have time to talk now, but I'll call you later') has lots.
But nobody knows who she really is -- not even she does, she's spent so long being what she thinks other people won't dislike!
You can't really trust that this person would have your back in a situation where you were being exploited, because they haven't even got their own...they're so scared of someone not liking them.
Exactly. I've heard my mother nodding and 'yes' ing along with a nakedly racist 'friend' because her fear of being disliked dominates what she actually thinks is right and wrong. She has allowed it to govern her entire life, and to cripple her relationships with other people. And yes, she doesn't even have her own back, which is the saddest thing to witness. And her terrible loneliness, after a life spent (she believes) putting herself out for other people.
