I can be fighter for love only when I have the feeling that it is going to yield something fruitful. Sometimes, we don't need to fight for love because the fight itself could be our destruction. We need to know when to let go especially if the other party is not willing to fight or is indifferent about the situation.
I'd say fight for love sensibly. It is really disappointing when you fight for love and end up realizing that it wasn't worth fighting for to begin with. If I stand to gain happiness and more than what I lose fighting for love, then that is a quest that I'm willing to take. We all deserve to be happy regardless of anything else.
