My father in law was married in 1947. He was a Methodist and was married by a justice of the peace. He divorced his first wife who was also Methodist. In 1955 he was remarried to a Catholic in the Catholic Church. He was still a Methodist.
He didn’t get an annulment. There was a form the parish priest got him to sign stating he was not a Catholic and did not get married in a church. He died at the age of 80 still very much a Methodist.
Sad story. Sorry to see how it ended.
