It's a complex thing, this idea of moving in the hopes of starting over. On the one hand, if we constantly run into people that hurt us or even, then moving is a good idea. On the other hand, if we're easily hurt by anyone, then wherever you go you'll find people that hurt you.
For the record, I've moved a few times, mostly because of college, grad school, etc. I've also changed jobs several times and sometimes that can make a world of difference. Then again, one job becomes a lot like the last job and unless you find one that's perfect (unlikely)…
The town I lived in where the abuse occurred was about 2000 people. Even worse, we didn't live in town but in a group of a few houses, in one of which lived the family of evil. We moved then to a town of about 15,000, which was a big improvement, but by the time I was out of high school I couldn't wait to leave and get away from people that didn't seem to have any empathy.
Now I live in a suburb of a very large metropolitan area. It happens to be a place that "they" say is very accepting, tolerant, etc, etc… well, up to a point. There are all sorts of exceptions.
