What on earth makes you think this? She lives with her parents who are still happily married after raising four children. Both of her older sisters are married and the oldest has kids of her own. Nerissa seems to very much want the same thing for herself. Maybe she doesn't want to have quite as many children as her sister does, but she definitely wants to get married and have kids someday. If anything, she seems like one of least likely EN members to have those sort of issues.
