I spent my last two years trying to have a redpilled mindset and life and at the same tame I tried to maintain my relationship with oneitis. With a decent sex life and lots of red flags when I finally thought I found an unicorn. 

She made a new friend. At first it was not a big deal but later on I felt that something is wrong and at that point I began to slowly lose my frame. We had a fight and later on everything went down as I clearly lost all my frame over her and started fully thinking blue pilled. I litteraly thought "if I show her how much I love her, everything will be alright."   After 3 weeks and now today I learned that this two are together. And now after I hit my face to face of truth, I still have some questions in my mind.

-I am quite good looking, have a succesfull life lots of hobbies or so. Why would she start a ltr with someone worst?

-should I block her?

-Should I beat the fuck out of the guy. People will learn that she cheated me and this will damage my reputation. If I beat him whould that be a "dont fuck with me" sign

-I feel quite depressed now how can I motivate myself.
