When your ready just book a flight and when you arrive they will do it all for you will cost a bit but they open bank account and do all paper work just sit back relax takes about 3 to 4 weeks they cover all your expenses etc. All they need is your passport.
Never allow wife to control YOUR money do not allow family to move in don't have a child they can blackmail you with make sure you have enough money in hidden bank account if you need to escape.
Just come do it here in Thailand on tourist visa all they want is your passport at a visa agent at worst you may have to get an extension for an extra 30 days. I gave up trying in Australia was stressing big time so just came out went to agent paid fee all sorted no stress opened bank account also. Just do it.
