Hello guys I'm 16 and I consider myself lucky to know about the reality of girls at such a young age. I too wanna be a red pilled guy. Could you please help me out?

Please tell me the reality of girls no matter how Harsh it sounds. I've been blue pilled until now . My gf with whom I was for 3 years was cheating on me all along. She was randomly sleeping with guys and once I got to know that I knew I needed to go red pill. Give me some advice.
