I am having an issue with my friend. She has just become very blunt and distant with me after I had to cancel seeing her two times. The first was when I hurt my knee badly so I couldn't meet up with her. The other was when I was urgently asked to cover for a colleague who had to go off sick when there was noone else available. I have offered her a third date to meet up with her but all.she said was cant be helped. Don't know what to do as it's not as if I'm making excuses not to see her.
