How can I get through to my ex, please help?

I know he has emotional issues that stem from his mother growing up, so he has trouble in relationships with women and fears of abandonment. He's broken up with me again over something silly, and now refuses to talk to me or respond to anything. He's shut down. I know this sounds absurd and I should probably just move on, but when you love someone so much, you want to at least help them. I know he loves me. He's told me himself he has issues. But then he goes back to denying it and playing the blame game and looking for ways to be angry at me and not speak to me. Is there any way I can get through to him, to help him see, to try to get him help? His family is not supportive, they all live far away. He's all alone.
