Well, this is most unfortunate to hear. Frankly, yesh you lack
the tactical advantage of not being in the same uni as her. This is
aggravated by the fact that you got a really persistent love
rival.
I say give her up. You deserve a better lady. NTU girls are rather
bad choices as gf because they are more villager like, more
gulliable and more soft-hearted. Thats why she can be easily
manipulated by your love rival. So this is something you must
consider carefully.
