Leo males: How do you act when you're mad?

Not interested in getting back, just understand the leo mind. Leo ex wanted to take me on a vacation so we met up in Vegas.(we live in dif. cities) Fun but got into a big fight. Bottom line: He would make snide comments & eventually made me feel very bad. That mixed with some alcohol and what do you get? A huge fight! I felt very disrespected so I went off with my girlfriends(who were also out in Vegas). Since we didn't fly out together it was cool & my flight left the next day. Only communication was some convo about me trying to see if I left a couple things at the hotel rm. The back in forth was cordial. But after that nothing. I'm not saying I don't have any blame but in this situation I know he did me wrong. However, I was the adult and at least apologized for my actions but him absolutely nothing. I'm not trying to get back together and going back to being friends is very doubtful but I just want to understand the male leo psyche.
