How to win back a woman’s trust after betrayal

Two months ago I felt like I was the luckiest man on earth. Today I feel like the unluckiest. My girlfriend recently broke up with me after a two-months relationship because she discovered two chats in my phone. They were flirtatious, I admit, but nothing serious. For context, my girlfriend is extremely beautiful. She won beauty pageants in college and she is currently a model for various beauty products.

No body count. No baby daddy drama. She is a church girl and very close with her parents. When I tried apologising, she commented that I'm just like other men and blocked me everywhere. What do I do?
