If you find someone better, I won't fight for you.
Would you tell your boyfriend or girlfriend that you wouldn't fight for them if they found someone better? What would you think if your boyfriend or girlfriend told you that if you found someone better than him or her, then he or she would let you go without a fight?
Also, this pertains to when you first started dating. On your first date during a serious conversation your boyfriend told you that if you found someone better, he would let you go without a fight.
