I brougth my exwife and our 2 kids to my country 18 years ago. I never regret that.Im often in thailand but just as a legal tourist. I only rent when im there..easy just to checkout and no headache after i went back home.I choose to not have a gf or wife again. I love my freedom without no problems.
I build a house in surin long time ago..paid only 360.000 baht that time.Not a big loss.
Now my exwife and our kids work here and make good money and everybody is happy. I will never ever invest anything in thailand again. Not because i cant..its because i dont want.
