Personally, I have always found guessing at the motivations of others to be a frustrating and fruitless endeavor... I can't even tell you why I do the things I do half the time. If you asked him why, he probably wouldn't be able to give you an accurate answer. You need to focus on staying healthy yourself, making your decisions based on what you know is good for you, and refusing to be a human yo-yo on a daily basis. Would it be a bad thing if you moved along, met someone new, and had a man in your life who could commit to you and have a loving relationship with you? Sounds great to me, but he's telling you it wouldn't be. It's that type of inconsistent logic you should look out for. He's keeping you off balance so that you can't get your feet on solid ground and make a run for it!
