I have a male friend who started seeing another mutual friend (female) they've now split but are still friends. Anyway, female friend is poorly with lots of issues, eating disorder etc.. Been off work. I was talking to male today by text, about something he and I are doing together. Thought she may like it but understood if she's too poorly etc.. texted him to say I was ringing her. Had a long chat with her, she cried a bit said she'd loved the chat and could we meet for coffee and that she does fancy doing the thing. Note, I'm closer to him than her but really like her, it's just a newer friendship. Anyway, he texted during the convo to say no, don't ring. She's so fragile right now and is paranoid 
When I came off the phone from her she was ringing him to say she is going to join us in the thing we're doing. He had said no way would she.
Am now thinking I shouldn't have rang? Haven't heard back from either yet and it's been an hour. Hope I haven't caused any problems?
