He says he is. dh is an only child but his du is a similar age.They lived together as teens.We have not seen him in 6 years and have not met his kids. mil does go back to the uk every year and does visit him but it is always a long journey for her to do it and I thought he would have returned the favour by now since she is been here 8 years, visited her brother every year and he is never been here.
