Cutting off a friend but she won’t get the hint?

🪐 E.T 🪐

So I don’t explain the full situation because it’s too long, so here’s the very shortened version. I have a friend that I’ve wanted to cut out of my life for a while - in fact I’ve tried to a couple of times. I told her I didn’t want to see or speak to her anymore because I feel drained every time I spend time with her and so on, and she ended up guilt tripping me into talking to her again.

I won’t lie, she has been through a lot lately and even though she has been getting professional help for her mental health she still uses me as a therapist when I have enough going on. I don’t like the kind of person she is and I don’t want to talk to her anymore, so I gradually stopped talking to her and it’s at the point now where I haven’t replied to any of her messages or facebook comments for a couple of weeks but she just won’t stop. I didn’t want to block her because I didn’t want to hurt her feelings but she just isn’t getting the hint yet. Do I just carry on ignoring her or block her on everything?
