Sue says she hasn’t seen her younger sister, Denise, in six years because of how controlling she claims Denise’s husband, David, is.

“David does not want my sister to have any kind of connection outside of the household,” claims Sue, noting that she has had to text in secret with Denise so that David doesn’t find out.

“He believes that if somebody else is involved in her life, he won’t have control over her,” she continues.

“Life is tough enough right now without Sue butting in,” says David, claiming that his sister-in-law tried to “meddle” in his marriage to Denise. David says he has “trust issues” with Sue and that he doesn’t want her in their lives because he is trying to prevent “unneeded drama.”

Watch the video above to learn what David claims Sue did to earn his mistrust.
