What she (Sea) said. Perfect.
What I want for you, Ales, is for your yearning for him to be a stand-in for the love and support you SHOULD have gotten from your parents...not to drive him out of your life.
So you can have a good brother, just a peaceful connection with a decent human, later in your life.
(Obviously, this comes too from me having severed my connection with a brother who was kind of a monster to me.)
That's why I press you a bit to lighten up.
Even a simple, check-in kind of thing with him now and then that has NO drama and NO demand in it, if you practice it faithfully every month for a couple years, could show him that you are not going to = stress and pain, in his mind.
It has crushed me in the past, to learn how people really do not want to take on the intensity of my emotional needs.
But I am grateful I learned it. I can still express them, and have them met, IN SAFE SPACES. Like here, with trusted friends, in some spiritual settings, or with a therapist.
But the biofamily? I need to treat them as pleasantly (and lightly) as I would neighbors with whom I want to maintain comfortable long-term relationships. Hell, maybe even "relationships" is too loaded a term. Associations. That's it.
If you want a lifelong association with your sibling...I think that a more-cordial, even more-polite-neighbor, is the tone to take for a while.
Maybe, as he matures, he will come back around one day to wanting a heart-to-heart kind of connection in which he, too, can talk with depth and insight about your traumatic origins. But the only way that could possibly happen, in my opinion, is if you stop pushing him for it. If it happened as part of his own readiness and growth, then you could be--then, some future year or decade--glad it did.
But in the meantime, you deserve courageous hearing, and steady support, from OTHER people. Because that's functional. And probably best for your long-term healing and potential for happiness.
Hope that's useful but please toss whatever's not.
love,
Hops
