(((Suzy))) sounds rough.... I think avoiding drama with these friends is a really good idea, but perhaps dumping them outright is a too drastic measure? Do you get anything positive from them at all that would make them worth keeping in some kind of respect? If not, then I think you're doing the right thing, but if they are there for you at times when you need them maybe a wiser course of action would be to limit contact or set some boundaries...
