Could be possible that the dad is a cuck and Jeannette fucked around on him, and the kids aren't his. I mean, he seems pretty spineless and just seems to go along with whatever Jeannette wants. Have we ever seen Greg's (is that his name? I can't remember) side of the family? Like most controlling women, Jeannette's side of the family is heavily involved, but I can't recall of ever seeing Greg's parents or any of his family, nor do I remember hearing of them being mentioned. A lot of controlling women also prefer their spouse to have no contact or very little contact with their families, whether it's because their family doesn't like them (the woman) or they're afraid of the influence they have over the spouse which would go against what the woman wants.
