Question concerning friendships

Friendships - when do you know that your girlfriend is giving you a message but skirting around the real issues?  Why does she avoid you when you call and make excuses not to get together?  Why not just speak the truth in a way that is kind but not just self motivated?   She used to be my hairdresser and I stopped seeing her as her cuts were unattractive and she forced her styles on me instead of what I wanted.  I knew I could not continue so one day I cancelled and apt  and then it seemed to put distance between us.  But then Ihonestly said I had found another lady and left it at that.  I keep reaching out in holiday invites and niceties but her response is oh so cold.   Guess I know who not to invite for dinner anymore.   Time for some new friends to inspire me.
