Relationship help?

You have to follow you heart and instincts. No one can make your decisions for you. No one can live your life for you, only you. I hope you make the right decision. However, he is saying that he did not want you to feel attached to him, maybe he was trying to tell you that he was trying to protect you from being hurt. I don't know, you said he used to play mind games, could he still be. You know him better, this has to be your decision. But, good luck and future happiness.
