Hey , i also thought about the same thing : if love is worth the pain!!??
ok im dating this girl now ok , we really love each other, but this one day we were having this huge fight ok and she sorta dumped me , but bing the person i am, i got her back and after a long discussion we were both back in love. she was crying, thats how bad she felt.
so my final answer is YES i actualy do think its worth the pain to fight for the one you love;):
