<human>: Could you distill the essence of the text into 1-3 sentences?

Well a few years ago I'm told that her parents had a very messy divorce, which was pretty hard on her. She doesn't see or hear from her often and her mom makes promises she doesn't keep and/or ignores her when she calls (doesn't call back either I think) this obviously is hard on a teen girl especially now in her life (or so I've read) on top of this she hates her dad's new girlfriend (they've been together a year I think) because she says she treats her badly and is two faced but the girlfriend tries to get her acceptance and help her. All that boils down to mommy problems and I'm currently being as supportive and loving as I know how by listening to her and supporting her and not getting angry  when she lashes out (that's not a problem for me, I generally have a not give a fuck mindset about things done against me) ok. How do I do better? What can I do to help her?
<bot>: For all you lazy people like me out there; Mommy left causing a hole she can't fill and I need to know what else I can do to help. Please Reddit, I hate to see this girl suffer
