I think the first verse is "hold me up 'cause I think i'll fall into you"
And I think the ending line is correct. She's saying "you can't come back". I'm guessing she's referring to her ex-bandmate Sam Quinn and telling him that once he lets her go, there's no coming back from that. She's married now and has a kid, so that's proof enough that she meant what she said.
