Am I being totally Unreasonable

If I am at my moms house
and while I am there someone
comes over that I am thru with
being their friend because its
to much crap and drama
that I ask my mom while I am
over she cant be.

I feel that its my time at my
parents house and while I am
there she shouldnt be aloud over there
she can come over when i leave.

Shes not even sorry for the crap she pulled
and some of the things she did can
never be undone they were
moments in life you didnt want to
have ruined or miss that she
either ruined for me
or made it so i missed them

So she came over, I left
and thats the way it is if
she is welcome there than I am
no

Is that unreasonable???
