most of the comments here sound right.....Everything is fair in love and war. But would you kill your dad in a war? Think abt it. Marrying a cousin is a blatant deviation from our social norms. Even sexual relationship alone is very condemnable..Now you two are in love...so can still be best of the friends and be in a good touch for the rest of your lives so u don't miss each other...that's the only solution I see here.
