Psycho girlfriend, how do you get rid of an emotionally blackmailing cancer chick?

Cancers are very clingy and undeveloped Cancers are particularly nasty to deal with because they're so subjective. That's also a maturity thing, not a sign thing. If your friend is as whipped as you make him out to be, he probably won't realize how toxic she is until he's lost *all his friends*. While I get you don't want to be loyal make it a point you're not going to associate with someone who let's their SO treat their "friends" that way. If he's smart he'll realize what's true and what isn't, and if he's dumb... well, then you didn't need his friendship anyway.
