Even with earlier martial issues, this couple is practically gaga for each other, especially in present day (i.e. after the point when Nidorino became more affectionate). Either way, the idea was to have a couple that went against the negative stereotype you may see in some married couples in fictional media. After their children, they love each other more than anything. Nidorina, obviously, loves Nidorino about five times as much as he does her, which sometimes makes him uneasy. Although not clingy, she isn't above pouncing him or pulling spontaneous stunts (this is one marriage that's far from predictable, that can be said). Still, they appreciate each others company and wouldn't trade what they have together for anything in the world. If only more spouses could love each other as unconditionally, this should be a new trend.
