My boyfriend broke up with me in a text message

Yeh, it's true. The man who is supposed to 'Love' me and whom i thought the world of has said: this is it in a text message. He said he wont answer the phone, answer texts or answer the door. What kind of person ends it with a text message? I loved this person, spent lots on him for gifts, nights out etc and he breaks up with me in a text message...what kind of person would do this?
