I think it's about a guy who's been mistreating the girl he likes and it's an apology to her. Saying it's not her fault he doesn't do what he's supposed to, or that he doesn't deserve her. The "what your afters not your fault" could mean she's looking for somebody else but he doesn't want her to go and leave him, even though he understands she's got the right. The "happy ever afters what your taught" could be saying, she grew up looking for the perfect kind of love and that's not what he's giving her so she has the right to look elsewhere though he doesn't want her to.
