Well from what we just learned it would also resolve the spell issue, she just need to do like her mother and pass on the powers to her child. The conflict between the spell and power would be resolved and she can live happily ever after.
TBH, aside from the spell on her heart, everything would be solved if she just married Fian and moved in with him (she obviously likes him...). He's from another country so she'd never have to see her shitty family ever again, he'd be able to protect her from any enemies, and everyone there likes her and respects her.
