OP You make your own choices, of course, but for heaven's sake don't base them of a lot of half-baked and incorrect assumptions.
Have you read any history - serious history, the result of recent research? Or met anyone with a happy marriage? Sounds as if you haven't.
Christian marriage - the only form available for the majority of people in the UK for more than 1000 years until 1836 - gives three reasons for marriage. None of them is 'patriarchal'. These three are very clearly stated in the standard C of E wedding ceremony; the wording has not essentially changed for many hundreds of years:
(1) to have and to care for children
(2) as " a remedy against sin, and to avoid fornication" - this applied to men as well as women. Nothing about "controlling women's sexuality". Men as well as women were meant to be 'continent' (ie to control their own sexual behaviour).
(3) "for the mutual society [= friendship], help, and comfort, that the one ought to have of the other , both in prosperity and adversity. "
I think that most couples - married or not - would still aim for that today. Friendship, help and comfort are very excellent things to have.
From 1836, men and women could get married in a Registrar's office. Nothing patriarchal about that ceremony, either. Indeed, today, brides and grooms can write their own Registry office vows (ditto for civil partnerships and same-sex marriages). Bride and groom both equally have to promise to take each other as legal spouses, before witnesses, and to declare that there is no legal obstacle to their marrying, but that is all.
As others have said:
There is no need for any fancy wedding celebrations whatsoever.
Where on earth did you get the (daft) idea that a person's identity - male or female - changes when they marry??
Also:
Women have NEVER by law had to change their name on marriage - and, in the past often did not.
Mrs, Ms and Miss are all abbreviations of the same word, 'Mistress' (meaning = respectable adult women.) Married or not, you can use whichever you like - the titles have no legal meaning.
HOWEVER, in the past, the civil laws and social customs of past SOCIETY were "patriarchal" - though this had nothing essentially to do with marriage. Civil laws gave men very, very unequal rights over property and also various rights to control the women in their family (that included children and other dependent females, not only wives. This - alas - included control of women's bodies, as well as of their freedom to act, to work, to study etc.)
Social expectations - from men, from religious and civil institutions and from disapproving other women also controlled women much, much more than men . (For eg, the famous 'double standard' (men could have affairs - though they might be criticised for not being able to contraol their 'animal' instincts; women on the whole could not (though some certainly did. As far back as we can read, literature is full of stories of love and lust and jealously and infidelity....by women as well as men.) )
Once married, women AND men were intended to fulfil the sexual needs of their spouse. Women could - and did - complain about male neglect or indifference. But the lack of reliable contraception made sex very much more problematic and potentially dangerous for women than for men (pregnancy and childbirth could be fatal) , so we can't say that past women's attitudes to sex were the same as they are today (ie fun for it's own sake). Remember Princess Anne saying that having children "was an occupational hazard of being a wife" ? I think most women in past centuries would have felt that. And there is even evidence that some women were pleased and relieved when their husbands took a mistress; it made their own lives less risky.
Above all, there is a vast amount of research and discussion as to what women in the past wanted out of marriage. For many, romantic love was not top of their list. Nor was sex-for-fun. Both might - or might not - be pleasant to have, but marriage was first and foremost a practical arrangement: much more important was a roof over a woman's head, food to eat, a respectable position in the community and some sort of income. Men wanted wives for practical purposes, too: cooking, cleaning, children AND companionship . Plus extra income: many - most - ordinary women worked - often together with their husbands - at various stages in their lives.
Turning to today:
- Why do you assume that a relationship will inevitably have 'issues' (I presume you mean problems)?
- Any partner - married or not, whatever gender identification etc - who forces themself on an unwilling partner is comitting a crime. Do you really, seriously, think that most relationships involve criminal acts? Sadly, there is domestic abuse - too much of it. But it's not the norm.
Two final points. You don't mention 'love', for an adult partner or for your imaginary children. I don't mean romantic love. I mean respect, consideration, thoughtfulness, tenderness, caring, sharing. Children as well as partners/spouses need all that. And I can't imagine how any relationship - including parent-child - can possibly work without loving compromise, from all involved.
