It's not likely that your soul will be changed but it might affect your view of the place. since you seem adaptable, the best decision is probably to settle down wherever your wife is from, if she would like that. I was originally going to buy a place in Hua Hin area, but my wife had no friends there and it would not have been as nice as being in her village. And I actually enjoyed living in a small farming village with her family around. I had internet and we could go away whenever we wanted. It was actually a secure and comfortable way of life.
And I would visit friends in Pattaya - the first moments and say in town, with all the bright lights and activity, was exciting. The 2nd dau, not so much so and the third day, I was ready to go home.
If your mindset and values can be distorted at this age, then it wasn't your true values.
