Meet this friend on a weekly basis for coffee/lunch. Less if I can help it. She's very self absorbed, chat is all one sided. She doesn't ask about me and what's going on in my life, just what she's doing, and her latest catastrophe (her Next order not coming on time, for example). I'm planning to gently back off from her, as I'm getting absolutely nothing from her. I was a big support to her when she had a crisis earlier in the year, and I know that if I were in a similar position she wouldn't reciprocate, nor would I want her to.
Anyway, it's her birthday next month and I don't want to buy her a gift. We're not close, and I want to be backing off. How do I tell her? And in a nice way?
