Bobbi Bostian wrote in a public Facebook post on Monday that she met David Bostian in 1985.
"He was the most kind, caring, thoughtful, loving man," the post said. "I KNOW this man."
Bobbi Bostian asked people to not "believe the lies spewed" about her husband and said she prays the allegations against him aren't believed "over what those of us who know and love him know to be true."
David Bostian was found dead after he shot himself Friday morning at his home at 3304 Tipton Court in Wilmington. This followed public allegations made against him about having an inappropriate relationship with a 16-year-old student in 1992.
