I don't know if the dev wants us to like her or not. She started redeeming herself in the main game but then we see what she was like and she is very similar to her mother.
I'll never say never, she may redeem herself properly one day but she is a hard character to like.
Sorry, I don't see how she looks like her mother.
Yes, she cheated with the person she really loved. But she didn't lie, manipulate, or pretend.
For me, this is the story of an insecure person whom, in her opinion, no one has ever loved.
That is, to be loved is her main desire and motivation.
- the hope for the return of the father, as the hope for love and care. That's why she treats Frank so badly.
- the fear that Frank will separate her from Abigail, the only person close to her.
- looking for love and care (looking for "daddy") she easily trusts guys and rushes into a serious relationship.
And in the end, she finally realizes that Frank is the only man who truly cares about her and loves her.
At least. that's how I see it.
Sorry for my English
