asalamu alaekum brother,
first thing, love is not haram or anything
but one thing must be kept in mind,
we have to follow the guidelines,
love is not something which should affect your life so much that you leave everything if you cant marry the one you fell i love with.
if you cant marry her, simply forget her.
dont waste her prercious time, she ll easily forget u, women usually do
if you dont want to make her life miserable, dont contact her and leave her alone
get yourself busy with something
if however there is a way, which usualy is not in socially retarded places like the subcontinent
then go for it with all that you have.
but of course everything has a priority, dont mess up your priorities
may Allaah help you
