Depressed

I have been divorced for 5 years. Dated several different men. I thought i finaly had a good guy. I did have a good guy. We got a long great. We dated for five months. i started to feel like he was giving me the cold shoulder. My concerns were confirmed. He wasn't returning any of my text messages. Finally I called and asked for a return call. He did call me. I asked if he wanted to call things off. He said he didn't know. Then I told him he owes it to me to be honest. He said his heart is not into it. I cried for days and I'm still cry'n. I called him two days later and asked if we could talk. He answered and said sure but he had plans that night with his kids and he'll call. Well there was no call. So the following day - I showed up at his house. He didn't expect me. We talk for five minutes. He tells me he doesn't feel close to me but wants to remain friends. He hugged me twice. He told me he puts up this wall in relationships and I told him that not fair to him. He claims he may be single the rest of his life. He was married for 15 years, I to was married for 15 years as well. I know he likes me. What I want to know is what does he mean when he says his heart not in it and he is not gettng close to me? Should I wait a few weeks and try to contact him? I miss him so much. Out of all the guys I dated he was the best. He has been divorced for 6 years but still does things with his four kids and his ex wife. Should i just move on. I am not a bad looking women and have no trouble getting a man. Men usually fall hard for me and I break their hearts. This time it was me who got hurt.
