To really settle may take a while but to feel comfortable especially with you all ready knowing your hubby well should not take so long. Although you will of course be seeing him in a different environment.Im guessing he will have friends and family he will wanna catch up with.
For the wife to fully settle its taken a good few years but by that i mean she can understand well Western thinking and way of doing things. She understands the pace of life and can handle day to day pressures with ease. She can converse with a local girl of her age and have them think she lived here all her life asking her what school she went to
From what I have read from a Thai site similar to this Thais find it many times harder to settle in the west than a Phill does. Firstly English all phills understand and of course read English even if they dont speak it so well at first.So for example a Bus/train or a high street is not such a scary place as all the signs are easy to read..
Another for us at least us as a couple does seem to be as Christians straight off they seem to have something in common with your friends and families ie chatting about basic beliefs (which for many of us are still very much based on Christian values, the national holidays and able to celebrate them even if its just family gatherings and work holidays..
A mate i knew better and hung round with more in the early noughties had thai girlfriends and compared to my Wife and other Phill ladies i knew they did seem to have far bigger problems conversing and understanding British way of doing things.. The only one of his Girl friends who ever appeared to have "fitted in" had been schooled and grown up here in the Uk.
