Yes, obviously, a priest or pastor, should not date someone under his pastoral care.
However, it is not the priest that might cause the pastoral issue. It is the women looking at the priest as sexually desirable and a possible husband. I recall, even in the Catholic Church, a priest being called "Father what a waste". This priest had a following that went out of their way to try to do favors for him, and even followed him when he moved to a different church. Obviously, this could be a much more serious issue if the priest could actually date and marry.
