I'm officially dumped

So I've given my now ex space for months after getting off to a great start in the relationship. I gave it her because her life was in chaos and she was under immense pressure. But I always had the nagging feeling that it was really all over. This even after she had promised to move in with me and even in our occasional texts she told me she loved me.
But tonight after we'd started talking more often again she said she didn't want to be with me anymore. I feel disappointed and angry. I've kept my life on hold to accommodate her return and yet she won't be. Now I feel lost too and unlovable all over again.
