CurtWild excellent post at the beginning of the thread."Erosion and dependence" is a great phrase. I often struggle explain it, I may now borrow that.
Jan I'm tempted to tell you just to fuck off to the far side of fuck. But instead what I will tell you is you just. Don't. Get. It.
Abuse doesn't just happen. It's built up, and even when the physical damage is huge, the psychological damage is worse. It happens slowly, until eventually it's bad, and you don't realize how bad, and you don't know how to get out. Sometimes they will threaten to take your children away, beat them, kill them or you, and it seems the only way to protect your children is to stay and be abused, because if you're taking it, at least they're not.
If only every victim of abuse had the support and resources available to leave as soon as it happened. If only.
I suggest you learn some empathy, thank the stars for how lucky you've been, and don't pass judgement on situations you have no scope to understand.
