Directing DFH

Not a massive die hard fan but over the past year ive been loving TSOU and I also really love a lot of songs from DFH. I understand that a lot of it is about her and her mum's relationship? Need to register to all of it but a lot of the songs I like are probably the ones about Paul I'm guessing? Have they been on and off a lot? It feels like he has definitely broken her heart a little or maybe she broke hers herself kinda ? Thoughts ?
