'The ex catholic priests I know all left to get married, and still have the belief, and to be honest all three of them would still be clergy if they could get married. '
My uncle, my dad's sister's husband, is one. He was born in India, ordained at the Vatican and an Oxford-educated physicist (now retired).
He met my aunt her first year at university where she was training to become a teacher, and they married 10 years later.
He says he left the priesthood, not the Church. She worked as an English and Religious Studies teacher for years and they are still very devout.
He believes strongly in returning to Catholic clergy being allowed to marry (this was only changed at the Synod of Whitby nearly 1000 years after Christianity was founded, before this, priests and sisters were allowed to married, only bishops and mystics did not).
In an odd coincidence, both my father's brothers married former nuns. Each of these women, however, had entered convent as teens not because they had a calling, but because they were from large Mexican families where it was common to give a child to God (not able to feed them all, probably) and had left religious life before meeting their respective spouses (they were both nurses, one is deceased but the other is still working as a nurse).
