Yeah, my sister does that... her kids are never away from her for too long, she spends a lot of time with them, spends a lot of money on them and making them happy compared to what we has when we were kids. I think they'll turn out ok, their parents don't fight in front of them or have meltdowns over money or get massively drunk and verbally abuse them, etc.
It's too late for me personally, but yeah, I don't know. It's the distance the abused tend to put between themselves and other people. While I don't consider myself directly abused, I've definitely been neglected and screwed with mentally, and my sister wasn't (she came 8 years after). It makes sense she doesn't have the same sort of problems I do.
Good advice for others, though, who might have the same fears.
