Well I had a few from bad choices I made--by far the wost was my 2nd marriage. He became very controlling & verbably abuseing--moved me thousands of miles from friends & family--refiused to allow me to make new friends & then walked out & left me stranded in that state alone with my young daughter.
He was a sick man as he had MS--something he did not tell me when I married him--but his nasty personality was not just from illness--I did not know him well enough to marry him. He became very nasty to live with.
