Mentiroso

He found out. My brother found out. About the line. About the crying. About it. I quote:

You cant do that.
Its not fair.
Its not fair to mom or dad.
Its not fair to me.

I dont understand how he could say such a thing after all the other things he has said.
Its so hypocritical for him to say i cant do that after telling me to cut myself as a joke.
He said he cares and i really want to beat him because of what she is...
Un Mentiroso, A liar.

More feelings once i sort out the rest of the confusion.
