Yeah, after giving this a little more thought, I don't know if she's using you.

She may just be in a bad place and need some help.

I mean, do you like her (in terms of being a friend)? It seems like you don't, but I just wanted to pose the question in case there is some friendship that is possible.

Sounds like your boundaries are being violated to some extent, but it could be beneficial to you (and her) if you set those out more clearly, you know?

Like, what is it exactly about her requests that makes you frustrated?
