I'm just speculating here because I don't really know anything about your life. I think it means he loves you but he either feels because of the past he can't get along with you, another woman could have his heart right now, or perhaps he loves you but isn't "in love" with you. I have found that often we can feel a connection or a spark around others yet they might not feel it on their side. I would suggest continuing to be cordial with him, so he feels good around you, while still moving on with other things in your life that make you happy. A happy woman is a magnet and could draw him back in, or could draw someone else who likes you in. You deserve to be happy one way or another. My best wishes to you.
