<human>: Can you give me the gist of the text in a nutshell?

OK Reddit, I was shopping with my best friend, when we ran into her boyfriend and his cousin by coincidence. We BREIFLY, said hi, exchanged friendly smiles and went our separate ways. About 4 days later I got a text from the cousin. He told me he went through a lot of trouble to get my number from my friend's SO. He asked me if I'd like to hang out, and I thought he was decent. Until I started talking to my friend's boyfriend and he told me he was a "player" and that he talks to multiple women at a time. This didn't necessarily shock me as he is very attractive. But then I learned that he BLOCKED me on Facebook because he has a GIRLFRIEND. Really, man? You deserve to be mauled by a blue donkey.
<bot>: Douchebag texted me, asked me out, I was interested until I found out he blocked me on facebook to keep me from knowing he had a girlfriend. Also learned he flirts with other girls besides me.
