Welcome, asortafairytale!
I went back once (was reinstated in 1981) and stayed in for another 18 years. One of the very biggest mistakes I ever made in my life.
But, as you and others here commented, the "tug" is tremendously powerful, especially for those of us who were raised in the troof, and for whom almost all of our family and friends were dubs.
I wouldn't trade the freedom and happiness I now have for all the treasure on earth!
