I say 'friend' because she vacillates between being a fun, creative, highly intellectual friend and being extremely negative, self-absorbed and toxic. I never know which side will present and I'm getting to the point where I just want to wash my hands of the whole thing and move on.
My last conversation with her was quite negative to the extent where it wouldn't bother me if we never spoke again. She, however; has been calling and leaving messages wanting to talk sometime, making it clear how much time has passed since I've called her back. I find this especially annoying in that she's routinely taken months to return my calls in the past and I've never given her any trouble over it, as we're both very busy people.
Any suggestions on going somewhere in between the passive-aggressive act of avoidance and the outright aggressive act of 'telling it like it is' would be greatly appreciated. My tendency is towards the latter and I could see that going very poorly and I'm not sure I want to risk trashing the relationship.
This is one of the few issues that's easier to deal with as or with a parent. It's easier to put distance into a relationship with someone who has kids, as they're busy enough not to have time to pursue much else. And if you have kids, they're a handy excuse for getting out of just about anything.
