<human>: Me and my boyfriend are in a relationship for last 5 years and i am so very much attached with him emotionally as well as physically. 

He also cares a lot about me and always make me smile. On the day before yesterday he went to a after night party at a friend's place. Though he asked me for coming with him but I said no because my parents were in the town.

For some reason they need to go out to visit my unle's place as he was not well so I decided to surprise him by visiting to the party. And when I reached there; I caught him red handed with two guys in the room. 

My worst dream has come true and now I do not know what should I do. He dropped a message yesterday that he always wanted to tell him that he is bisexual.

I am so depressed and can not make a decision. Please suggest what should I do. 

He might want to be with me just because of his family and fiends who won't accept the truth of him.

Can you give me the gist of the text in a nutshell?
<bot>: My boyfriend is bisexual and wanted to continue to be the same. I am annoyed and frustrated what to do? My life is ruined, 5 years long relationship and now everything is screwed up!
