I have revisited this this morning because MN have had a look and clearly decided that the OP is not just deliberately winding people up for the fun of it. And your lack of self awareness, Kelly is quite staggering!
I think that part of the issue for the OP on this thread is that the Narcissistic label has been wheeled out. That's actually quite a specific diagnosis with a specific set of diagnostic criteria and I wouldn't be happy at having it levelled at me by a group of strangers who were judging me on a few internet posts. And I'd probably argue against it too (Well I know I would).
However, self centred, selfish, ego centric, closed minded, self absorbed, arrogant... these are all descriptions of how you have come across in your posts, Kelly.
And the most infuriating thing for other people is that you have said things like, "And again, I don't see it is as narcissistic to want my brother to be happy, quite the opposite". Taking the label of 'narcissistic' away for a moment, because I don't like the way that term gets bandied about so freely, it's somewhat ironic that your defence against the accusation that this is all about what you want is for you to restate what you want. He might not be 'happy' by your standards, but he is clearly content by his. Whether you agree with that or not. And even if he isn't, it's arrogant of you to think you can speak to him and solve it for him. It's not about you.
Springy's summary of how the dynamic is perpetuated and justified, and of how family narratives get written and supported and how everything that happens is interpreted in a way that supports it is spot on.
You are still insistent that pretty much every single person on this thread has misunderstood or misinterpreted what you have said.
I think that you do need to consider the following:
MN readers/posters are made up of a diverse group of people of, differing experiences, differing socio-economic and education backgrounds, of differing levels of intellect, of differing expectations in terms of family, differing degrees of social understanding... etc... yet you feel that every single one of those people has 'misunderstood' or 'misinterpreted' what you are saying.
If everyone is 'misunderstanding' or 'misinterpreting' what you are saying/what you mean, then you might need to consider that it is your style of communication that is at fault, not every single other person's inference and deduction.
If you come across to your brother the way you have presented yourself on here, then I am not surprised he isn't really interested in you and your life. You sound like very hard work and he probably just can't be arsed.
He sends you pictures of his daughter because a) he is proud of her and b) he gets that sending pictures is something you want to do. He replied to your photos of your wedding, but wasn't quite as gushing as you wanted him to be.
Your judgement of him is startling.
Just get over yourself.
