What happened with are love?

My half brother

He is ok he can be a jerk and really mean at some points but other points he can be nice and sweet but that only like once a week like seriously but he is pretty cool
He is only my half brother because we have different dads my dad is named Anthony and his is Sean the one all my friends know
I have never actually met my dad the only time I saw him was at the races and I was little so I don't really remember him but it's ok
One day I'm going to find him because I have a lot of questions. All my family says is I look like him I act like him and all this stuff well I can't really say yes to any of those things because idk what he looks like so yeah
My mom said that he wanted a boy and since I was a girl he walked out but I think there is way more than that.
I just want to know more I have asked about him many times but everyone acts like they can't hear me
I think I have a right to know about my dad and if no one in my family is going to tell me then I will just go and ask him myself when I'm older
But yeah I know Sean has been in my life since I was little but see I can call him dad but in my heart he isn't really my dad I love him to death sometimes but just I can't really feel it he is just my step dad and that's all he will be
My mom is ok she has those moments when she just brakes down and yells at me but she is my mom and I love her I also loved just having me and her in are family there was no brother or dad or anything it was just me and her and I wish that was still the way it is today.
Yeah so there's that.😂😐
