Would you accept moving to another country and start a new life far from your culture and family?

Sometimes that's what people aim for. I'm personally thinking about moving to Australia and starting my life there

It's hard to be away from family, I wouldn't just leave them and go

Do you mean move away from your parents and siblings? or does this include moving away from you wife and kids also?

Because generally kids grow up and leave the parents house, but a husband/dad isn't supposed to just take off and leave

I would consider this if things are going badly in my current life and need a new start
