I am a silly girl and i always playing or joking around with him. Last time , his friend posted a pic said " I am gay and i have a small ****" on his snapchat and my friend and I was making fun at that. We both did that but he's only gets mad at me. After that , I texted and said " it's was a dirty jokes , why are you so serious " and he was like "hmmm" that's it nothing else , still mad. Should i keep bothering him or ignoring him? Should i say sorry?
