My ex is ignoring me

Ok, I met this guy (were are both 25) on a dating site, he was a rebound from a 1 ann half year relationship I came out of, unfortunately I fell for him. We were very serious quite quickly, saw each other often, he'd do anything for me. We even had a week abroad on holiday. The relationship lasted exactly 3 months. We broke up on 30th september, everything was great and we was happy, then he started busying himself and was talking of doing a 2nd job as a doorman that he'd previously done before meeting me, I wasn't happy about it as I would never get to see him. On the 30th I stormed out of his house (he lives with his parents) in a mood with him. Since then he will not speak to me, it's been a month now, he will txt me back now and again but ignore most of my texts and all calls (I haven't tried to call a lot though). He has some of my clothes and I have some of his, which a week after breaking up he said he will come and collect in which I agreed but he never came so I still have them. I saw him on the online dating site we met on a few days after breaking up and until this say he is always showing online on it (my profile is hidden but I can still search) I can't move on as I am not over him, he did tell me 2 week ago he hadn't met anyone, but I just want to know what to do. He is extremely stubborn. He even fell out with one of his best friends the night before I stormed out and I am in contact with his friends girlfriend and she has said they have not heard off him and he's ignoring them too. My instincts are usually really good and for some reason they are holding me back from getting over him. I even went to a psychic and she mentioned him in my future. What can I do? I wish I could move on, it was only a short relationship, I'm usually good at moving on but for some reason this is really hard. I'm falling into depression over it. I've even sent him texts saying 'if you do t want us to sort things please tell me and I'll leave you alone' and he won't reply. I should get the hint but something is not letting me give up. What do you suggest?
