I got married to a man who I had not slept with, and we didn't move in together until we got back from our honeymoon.
Traditional as you like.
We had no communication skills, and we didn't know each other well enough to realise how little we had in common.
Our 'traditional' marriage descended into controlling, sexually and emotionally abusive hell-hole, and our children were being modelled a relationship with little intimacy, even less communication and zero affection. A mother who was almost completely shut down and a father who was constantly furious.
I'm sure from the outside it looked peachy and would have had 'traditionalists' nodding in approval.
I'm now happily in an unmarried, consensually non-monogamous relationship, with a partner, a boyfriend, and a girlfriend, who all communicate well, and are there for each other, in all four overlapping families forming a village, who we can all count on for help and support.
There are, in total, ten children between us all, ranging in age from 7 to 20. who are all happy, well adjusted and thriving with several adults in their lives who they can call on for support, advice or help.
I'm sure traditionalists are clutching their pearls all over the place, but those who know us and have seen how it pans out in real life - including my DPs SuperCatholic mother, and all of our extended families - have to admit that it seems to work very well.
I know which setup is best for my children, and it's sure as hell not the former.
