I don't know where to post this, I have a horrible older brother...

He and his two brothers are much older than me, he's the youngest at 14 years older. He's in his 50's. They are half brothers, and have always been neglectful, mean, and abusive towards me and my full brother (who killed himself, I believe in part to us having no support from them and a generally mean, nasty competitive sibling situation.) They have always competed for our shared Father's love, and never been there for me at any of my events, bullied me, and this brother in particular has always gone out of his way to tell me all of my accomplishments were of no value and put me down and insults me in front of our father and in front of extended family. I think it also always had something to do with the fact that I am adopted. Our father passed away and left us all inheritance, but left me more. (Likely partially having to do with me staying and taking care of our father who had cancer.) Brothers are obviously put out by this and tried to take it from me, looking for an alternate will and also tried to take the money going to my dead brother (so, his children) saying it was a "mistake." They were not successful because that's not how this works.

Anyway, they barely ever spoke to me and now it's really never now that our father is gone. None of them contacted me on Thanksgiving, and it's my birthday today and they never contacted me over that, either. The one brother, the most verbally abusive one, sent me a text that was almost more insulting than if he hadnt done anything... It said "happy birthday". Like that is all that I'm worth. I've always been a coward with him, but I really want to text him back saying he has always been a horrible big brother and never deserved a little sister or a little brother. Should I do this? I think it would make me feel better to let him know, and yes, I really need to cut him completely out, and I think this will help me do this, I want him to know why before I go.

I know what familial support means as I am married now and have a daughter. I don't want him in my daughter's life as I know he will do the same thing to her that he did to me, or try to come in between me and my daughter. My husband agrees and can't believe how they treat me.

Do you have any advice as to what I can say to him over text? Yes, text is better as I can respond to him calmly and will get a chance to speak. In person, he would just yell in my face until I'm shut down from speaking, something else he has done whenever I have tried to talk to him. (He's a recovered addict and has very little skill in having a calm conversation.)

I dont want to repair this. I just want him to know, over text, as to why I want him out of my life forever.

Can you help me figure out what to say? I could just say nothing, but then he might just keep sending me these little digs over text. I also removed him from my FB because he puts him pictures of himself with his "family", ( his other brother) and never mentions or invites me, something else he's always done, excluded me and my recently deceased brother.

Thanks for any help!
