Hi half-life,
In the first story, my wife was deploring the people on the train for their uncivic culture.
The dark side of her not getting help is she is really disgruntle about other people.
These are some good observations you made here, and I think are a clue to potential answers to your question.
People generally develop habits like these in their childhood, to adapt to the limitations of their FOO. True, they get refined and changed as we get older, but what I've read from psychologists who take a developmental approach is that a person's overall emotional patterns or "grooves" are laid down by the time we are six years old.
Children notice what gets attention and what doesn't... .what behaviour gets rewarded and what doesn't. Many families have traumas and/or rigid beliefs around needs, giving and receiving, generosity, gratitude, etc. This can be religious or cultural as well.
Your wife may have learned in her FOO that giving was good, but asking for help or having expectations of others was asking too much, "taking advantage of them", etc. Maybe certain people were allowed to ask to have their needs met, and it was others' job to meet those needs without complaining or asking for anything in return.
The key though is
those needs don't just go away when we learn by early experience to ignore them. There's always a "flip side". My guess, and it's only a guess, is that she resents that her needs were not met and that resentment seeps out in the form of moralistic judgments on society "self-absorbed, no decency, uncivic".
I almost decided to move your post, because it seemed like it was a question about your ex and not yourself. However, I think this could be a good example for us to think about with respect to ourselves.
Your wife is telling a "story about how life is", if you will. "People don't help when I need them to. They are so selfish, indecent, etc."
So my question would be, who is this judgment really about? A few possibilities:
1) Her parents (didn't help her when she needed them to, or responded with criticism/impatience to her requests to have her needs met)
2) Herself (if the assertion of needs was punished or criticized in her FOO and labelled as "selfish", she fears the supposed selfishness and indecency in herself, which may not be selfishness at all, but healthy self-interest to get one's needs met)
3) Herself (she is actually selfish in ways she's not aware of)
So, why would someone want to adhere to such a story? When it looks from the outside like what she is doing, metaphorically, is dumping cup after cup of water that she is offered onto the ground, and yet keeps complaining that she is thirsty?
My understanding of this is that people only stick to self-destructive beliefs if they perceive that they are avoiding even worse pain. And that that pain will eventually need to be acknowledged and faced (this is where a skilled therapist can be really helpful... .emphasis on the word "skilled", in addition to clinical knowledge, the therapist has to have faced their own pain enough to be able to guide others in that way).
What that pain is for your wife, we can't know, and we may never know. But we can ask similar questions of ourselves.
What is your relationship to needs, and asking for help, half-life?
