Why did his best friend invite me to their chat ?

Okay I'm going out with this boy named Carlos which he is my boyfriend . He admitted to like me first and wants to date me . Me and him talk a lot on Facebook so I wrote on his status , and then his bros (friends) started writing . I noticed that one of his best friends (Jose) wrote a comment which I saw. Then out of no where he in boxed me telling me their not gay at all etc and I just said it was fine. Then he said he wants to add me in their group chat so I can pull a prank on my boyfriend . But since I didn't do it José seemed upset and started being mean to me a bit .
