He asked me for a threesome???😤😤😤

Sel

So there's this guy that I've been messing around with and we have been having a Friends with Benefits relationship for awhile. We've been getting along well and having great sex, everything's been going good...

Until he asked me last week if I wanted to have a threesome with some girl that I've never even met. A few months back I told him that I wouldn't have a threesome, or at least I wouldn't have a threesome with him, because I felt like we had some kind of connection, or at least I thought we did. It really pissed me off that he would ask me something like that because I really did like him, and on top of that, I told him that I wouldn't want to have a threesome previously.

Now he's texting me and trying to talk to me, but I don't know what to say.. I feel like I should cut this guy off because he crossed the line and didn't take my feelings or interest into consideration. (I don't want to screw a girl and this is clearly one sided because I know he wouldn't want to have a threesome with another guy.) But I don't know how exactly to put it without being too dramatic. What should I say?

Guys I need some help!! Thank you!

Also, here is the text of him asking me:
