I haven't seen you
I haven't seen you here before.
I haven't seen you in weeks.
No te he visto mucho últimamente.
I haven't seen you much lately.
Han pasado dos semanas y no te he visto.
It’s been two weeks, and I haven’t seen you.
No te he visto a ti por tres años.
I haven't seen you in three years.
No te he visto desde la secundaria.
I haven't seen you since high school.
No te he visto en todo el día.
I haven't seen you all day.
