Hey, I don't understand why he would pick favorites, that something jerks do, just stop talking to him. If he keeps on being rude, don't comment on their memes so you don't attract attention, but you can still look at his memes, then you won't get into anything hopefully. If he comments on one of your images, just ignore it and don't reply so it doesn't evolve into anything. I'm really sorry any of this is happening to you, buddy. It isn't fair, I know, just try to not involve yourself into any of their comments.
