It sounds to me like she's wishing that she could have made the relationship work, but it didn't play out as she wanted. She realizes this, so she starts distancing herself from him to protect herself from the hurt that comes with the eventual break up.
She transitions from baby to just his name, no more terms of endearments, no more intimate kisses, just friendly kisses then to simple hellos.
She reached the point where she's given up on the relationship - but is still extremely sorrowful about it.
