timro ama ko ra mama ko blood relation ta autai ho ni sathi, ani yo relation lai timi kasari bind garna sakchau?? , I know some ethinic groups of nepal adore this kind of relationship but you have to defend yourself from doing this. The result could be something that you don't want to hear or happen. Be a wise man and find somebody to start a healthy relatioship. And one more thing, do not just ignore your cousin, convince her about the dark side  and find somebody who would love her more than you do. Be a man! dough.
