Hello everyone very new to this but,Sorry it's long.

For context Summer of 2022,I made a post on my Facebook about not relying on family when it came to your time of need & support. I didn't name anyone,and for those who know me, know I'm the youngest of 9 half siblings. I had told a story of 6yrs prior at the time, that when I needed emotional support for a major surgery(partial hysterectomy for the removal of a golf ball sized cyst on my one ovary)they turned the conversation back on them. My brother Alan's gf said "Oh I could never do that " or Alex's gf saying "It took me 9yrs just to conceive my first" " Or that's quite selfish to have that done".First of all,I didn't choose it ,second I nagged my Gyno for 8yrs because I was in severe pain.For nagging so long about it she said she'd look basically to shut me up about it.She had found a huge cyst,she had scheduled an appointment for surgery.So after I had posted that on Facebook my two brothers Alan & Alex that I grew up with didn't message or call me,but chose to call our mom to bitch about it.Alan saying "You should watch what she posts" Alex saying "If she wants to see Rage I'll give her rage".Never mentioned names but the ones who were there through Skype verbally attacked me through our mom. Then December of 2022 came and I had texted a letter to both Alan & Alex saying I have tried to be apart of your lives throughout the years and you barely messaged me. And when you all did it was single word answers a week plus apart. I hope you have an amazing life ..good bye.My Alan messaged back,then called. He had blamed me for everything, how his life turned out,fights with his long term gf, how his kids & there disabilities,his life choices(mind you he is 4 1/2 yrs older than myself)are all my fault.WTF How is that my fault I said? He never answered then hung up.My other older brother Alex(9yrs older) called our mom and said I'm sick of you always defending her our mom said I'm not the two of you have always had an issue with her since she was little and it only got worse.Alex yells at our mom saying you know what I'm tired of you all, consider Alan & myself disowned never call us again. Throughout the the years since 2022, Alex eventually made up with our mom but not me.Alan made up with our mom not me. Last September '24..our dad passed away,mine biologically theirs only because he adopted them.After that Alan and Alex met my then boyfriend said they liked him..they did a tiny bit of work acted like the were conquering heroes to take time out of there life to travel to us then left. Our mom called me the other day said she spoke to my little brother..I laughed fairly good at that..a bit of an inside joke.My brothers are all older but I'm the tallest(6ft while they are in their words 5'7 on a good day). She had told Alan that even though I told her not to she told Alan after a bit of talking that my bf had proposed to me and I said "Yes". Now he's saying that I should call him,that he did all the calling which he hasn't blah blah.I told our mom the only reason my brothers are interested in me at all is because I'm a rising star on Facebook as a blogger/writer and that .And that not only has a man chosen to love my strong personality/will but he has proposed.Thats it,I told her we don't like each other,and have nothing in common.She wants me to be a bigger person ,because when she's gone I'll only have them.I said you are enough for me ,plus I'll have my fiance family as well,they don't even talk to you they vent at you about there lives. She said I know but could you try. MHmm 😒 AITA
