Don’t want to loose her

Male 18

I have been dating a girl for past 2 years , we are dying on each other, we love each other so much. We infact promised each other that we never cheat on each other .. The problem is she has been studying in girls school , Now she insists on getting admitted in co-education where both boys and girls study each other,, but I don’t want her to go there, because I’m pretty insecure about her and I never wanna loose her.. Moreover I’m scared as hell that she may talk to boys there….
I’m freaking upset,,,, Plz let me know what i should do…
