So I met this girl who lives in the apartment below. She is pretty clean, while I'm just a random drug addict trying to be clean. She had an ex bf who had a drug problem too, she also had her drug experiences. I really want this girl to stay in my life  as a friend or SO. 
But I don't know how I should handle this. 
Today we met and drank a beer together. I really enjoyed spending time with her but I don't want to become 'too bpd'?
