I don't believe that he is trying to hurt you but I think that he is very confused with what he feels for you. Also, unfortunately, it seems like he is not self aware and is ignorant of the responsibility he has to treat you with decency. To put it simply I believe that you deserve better than this, don't you?

I think he is making a mistake to treat you this way but I also think he is only human and he deserves forgiveness. I would recommend that you stop trying to get in touch with him, I know that is hard, but don't you think it's making things worse? Do you think he can really help you?
