My boyfriend's sarcasm is so elite that I can't even tell if he is joking. It is slowly driving me insane. He thinks it's funny if I can't tell if he's joking or not. Asking him to stop doesn't work.

Example:
>two of boyfriend's friends been dating for a while
>i've had trouble making friends for a few years
>busy, a lot of time with boyfriend and stuff
>made friends with his friend's girlfriend
>we're still "new" friends though
>boyfriend will hang out with them sometimes without me
>he'll text me saying that my new friend doesn't like this or that about me
>ask him if he's serious or not because wtf?
>im kinda sensitive about this, it's hard to make friends in general, I want her to like me because havent had female friend in forever
>bf lets me writhe insecurely in the thought of her not liking me
>maybe after a prolonged period he will eventually tell me he was joking.

This is like, the most asshole thing my boyfriend does. He does this to everyone. Just tries to set them up for pranks or make them feel like shit for a moment so he can get a kick out of it. He's like a fucking sadist. Yet when we hang out alone, he's super sweet.

I don't understand him for a moment. What do..
