Well you can't reallyask her not to go to college
because you like her.
If you really liked her
you would want her to get great education
and a career she wants
to be successful.
Or
you could tell her you will support her for the rest of her life.
And
you shouldn't be afraid of rejection if she's leaving forever.
Who will care in the end if you are rejected?
I mean, she won't.
She's going to college.
She will prolly get over it the first fuck fest that comes around.
But that's just what I think.
