Thank you for allowing me to answer this question.
Actually, Jerimiah was faithful to his calling and never married.
He, Jeremiah, was instructed by God not to marry and raise a family (Jer. 16:1-2).
He Remained single, and considered this to be an easy sacrifice.
The book of Jeremiah was written while he was in prison. Actually, Jeremiah spend most of his life in prison. The early chirstians had a really difficult time.
