Many women get upset when a man says he is playing the field. They just can't stand to hear the honesty and would rather he decieve her and make her believe she is the only one. If he does that, and she later finds out he has been seeing someone else, she is furious, when he told her from the beginning what he was about.
We need to listen and accept what we hear. If he says he isn't ready. He isn't ready and we have to let it be. Forcing a situation is never the answer and usually will lead to heartache.
People tell you who they are all the time. Listen!
