AITA for telling my SIL I got a boyfriend and not my brother?

I (19F) recently got a boyfriend for the first time.

I was super excited and posted about it on my Instagram close friends list and to all my most active contacts on WhatsApp.

This group of people includes some of my friends, some of my closer extended family, my parents, my brother, my sister, and my two sisters-in-law (SIL).

My other brother (33M) is not included.

She had her reasons for leaving him out.

To be honest, I don’t really talk much with him, and we have very different values.

We kind of have a difficult relationship. Obviously, we love each other, but we don’t really get along that well.

I didn’t purposefully exclude him; I just kind of forgot that he was even someone I should tell.

But she never anticipated he would react so poorly to be excluded.

He sent me a message today, really angry about me not telling him, and said that I was being a horrible sister.

He also said that I was an even bigger AH for telling his SIL and not him because they have been fighting a lot recently, and it seems like I am taking her side.

Now her family is giving her conflicting advice.

Most people are telling me to just ignore him, but my sister and some of my relatives feel like the jerk move was telling my SIL about it if I wasn’t going to tell him.

AITA?

Her brother was real quick with his wild assumptions.

What did Reddit think?

It’s entirely possible her brother thinks they’re much closer than they actually are.

The brother should really act his age.

There are multiple holes in the brother’s logic which this commenter cleverly points out.

Maybe the two siblings just aren’t meant to be close.

It would seem her brother’s blowup was more about his ego than the actual act of being left out.

He won’t be finding himself in their group chat anytime soon.
