Do you get along with your ex?

I parted amicably with all except two of my ex boyfriends and those two were from when I was in my teens.In fairness that first ex was from when I was 14 and I cheated on him.The second ex was when I was 18,he tried to slap me as we were splitting up.It did not end well for him.I have trained in martial arts since I was ten and retaliated.He even knew about my training and still tried to slap me.Bad move.
