I have a huge problem...

I really liked that guy and we went out like some times and then he kissed me and it was so great and all...
But after that we didn't see eachother for like two weakes. We did talk and all, but today we talked and it started like normal. We talked about music, films, stuff and than I asked him to tell me something and he wrote and wrote and there it was... The hrible truth!
He told me that after our first date he wasn't in to me anymore and that I am boring and that I just aren't so great and so on...
I first was like ok, but then I started criing and it was auful. He broke my heart and now I am mistrable and mad and feeling really upsaid...
Do you have some advice what do do next and about him? I just feel so alone so please help... :'(
