So what are the ethical rules in love? Is it 'Alls fair in love and war' or is it more complex? Situation 1: Now say I fall for a guy, and I beleive this guy has feelings for me. Now say I'm bestest friends with said guys recent ex. What should one do in this situation? What rules of engagement exist if any? Situation 2: Unresolved Ex's Mine and/or theirs. What should be done? Basically? What do you guys all beleive is fair in love and war. Is it a more traditional battle approach (marching smartly into battle and getting shot down with great honour) or the concept of total war (bomb the mofo's!!!)?
