The above article lays out the "rules of marriage" that no longer apply. Well, I've never even been in a relationship before. And for good reason: I prefer to avoid marriage and even relationships because I don't want to deal with someone elses problem a.k.a "family dynamics", usually the family of the spouse/partner such as children, exes, parents, siblings, enemies, and friends. I don't want to deal with someone elses baggage from another marriage/relationship. Breeders take an optimistic viewpoint towards marriage and family while I tend to disbelieve in the whole idea of marriage and family. Children are a burden that takes up time and wrecks relationships. I don't want to deal with someones children. Its pathetic that breeder women only get half an hour a day to themselves when childfree me has oodles of freetime. Your arguing everyday with spouse? Sounds very unpleasant and shouldn't be considered normal.
Whether marriage rules have changed or not I still don't think the dynamics involved in modern relationships is really worth it. The "new normal" really is a sign of a new dysfunction. Sure, life can be hard, but you don't need to make it more difficult.
