I haven't heard anything from him and I am worried. What should I do?

I dumped my boyfriend two days before Valentine's day.He made all these beautiful plans for us to spend nice Valentine's day he paid for spa for us and other entertainments. He spend a lot money for a beautiful diamond jewelry which was my present for Valentine's day. He bought a Holiday for us as well and paid a lot of money for it. We had a stupid argument , he shouted at me and this was not the first time he was doing this I told him I don't like to be shouted and screamed at and he said this is the was he express his anger. Then I told him not to bother me anymore and this happened via phone and texts.The same evening he came to see me at my work place but I completely ignored him and refused to talk to him. We have been together only for a month and a half but he was planning to spend the rest of his life with me, to move in to live together, he met me with his family. He changed many things I didn't like including he deleted his FB account. Since I dumped him and refused to talk to him the same evening he did not contacted me. I am very worried now if he is ok. I don't want to contact him in any way because this can give him wrong impression but I am really worried. He did not even activate his FB account. What should I do?
