I think the song's about the singer's first true love. It sounds like she left him completely heart broken and he's "never been so alone" before.
Looks like they had the whole "commitment" thing going on "and now i'm left with broken promises".
They vowed for forever and she took that away from him and all he does is hurt over it but he's saying that he can't handle the pain anymore, so he's going to move on.
