ay m8, i know what this is all about.
maybe your friend set you up? did you ever see the actual message / name of sender that his gf dumped her?
like maybe he did the kiss face just to see if you followup? and seriously, who actually says just randomly "im totes not gay i have a gf u kno :)))))" and then she just dumps him? what are the loving chances of that happening? Maybe he wanted u to take the chance? ;)
