It doesn't sound like she is in a place to be a supportive friend right now. If she was taking advantage of you, then she really wasn't a friend to begin with and you're better off without her. As wpowers mentioned, you don't know that she "got" he boyfriend to do anything, it's more likely that your message greatly upset her while she's in a really bad place and vented to her boyfriend who took it upon himself to vent on you. I think her lack of contact over the past six months says more than any response she might have sent you.
