Mairead Philpott is telling the court that many people describe her relationship with husband Mick as "unconventional" but that "for us it was a happy family".
She says she described Mick as her "guardian angel" when he arrived in her life. She said he "cared for me and loved me and made me feel safe".
Mairead says she was "scared" of losing Mick when his girlfriend Lisa Willis came on the scene.
She added that their family had grown for "love" and not for the benefits.
