What are the things that i can see through u

This really give me a bullshits (i wont use bad word that often >.<") But its really a pain in the ass when u knew that something is not meant for u.

Example;
-Since in the begining, i knew this guy doesnt have a honest friendship with me But i still friend with him
-I lied to him (another guy) and that that guy knew it because he say it out loud that i was lying and yet he shared his deepest secret with me after that without any doubt
-From certain point, I KNEW this guy (a total different person) has a crush on me and I played his feeling very deep
