Well written, Nisa.
We're humans and it's only natural that love will happen. We're survivors so it's only natural we'll protect our hearts, sometimes a little too dearly. We're always becoming someone, at least when we're young, so it's only natural feelings will change, we'll (re)discover ourselves and move forward.
As someone who's (thankfully) had a few heartbreaks, I can tell that love is worthwhile, despite the undesired inevitables that come with it regardless of our best efforts to avoid them.
