<human>: I feel like I'm really just submitting this for support because I just feel like no one can be trusted....this guy played me so good that I feel like he must have been a sociopath....even once convincing me my own brother was telling me lies when he ran into him with another girl out at 4am.

This probably sounds like crap because I'm an anonymous person on reddit but I really strive to be honest and open in all my relationships....I give a lot....I'm compassionate and understanding.  I feel like this opens me up to so much hurt.  And I just keep getting together with people who turn out to be just terrible and lie to me.

I'm still in shock that this happened...I had no idea he was seeing this other girl (who is obese and unattractive) behind my back....and we spent almost all our time together...I just don't understand it.

Are all people just selfish and horrible?  Is there any men out there that are caring and compassionate?  I feel completely hopeless.

Can you condense the text into a few key points?
<bot>: I've been wronged and hurt by this guy and I just feel hopeless when it comes to people now...I feel like everyone is selfish and can't be trusted...
