I was previously in PU a little bit, but recently got severe oneitis with a girl. To make a long story short, we dated for a year, I let her move in after six months (terrible idea) and I asked for a break six months after that which ended in our breakup. I was ready to marry this girl, but I started to get jealous, impulsive, angry and all around killed the relationship.
I was in the same boat 5-6 years ago. I discovered the PU community and discovered it was more just just about picking up women but it was about building a better life. I was on a journey to better myself. Having met Bravo and many of the guys here personally, I will tell you that you are at the right place and so early in life to learn from so many awesome people.
