Broke up AGAIN and I'm about to scream at someone!!!!

Yeah, he broke up with me again. I am so done with it. I am so done with it. I am so done with it. Why am I saying that???
Oh, his reason!!
I'M LIKE A SISTER TO HIM!!!
Dude wtf?!?!?!?!
Then I saw him today and he asked if I was still mad at him?!?!
Dude, hell fucken yes I'm still mad. I'm in/was in (?) l.ove with the boy and I'm like a sister to him??? Nah not mad at him at all.
And now the part I'm confused about....
Why am I sorta happy that he broke up with me??? Why?? I confuzed.
Love,
