@phillies I don't disagree entirely with your point. There are women who refuse their husbands sex, there are lazy women out there who fail to keep their end of the bargain. I think those sorts of women are horrid. However your view is limited. Here are some things to consider
Marriage is not 100% divorce rate. It remains around 50% in the US. So approximately half of marriages do not fail. Some are good solid marriages. The key is to be a good man, be able to recognize a good woman and for the man to be a good leader in the marriage and the wife a devotee to her husband's endeavors (yes while sacrificing her own interests toward the husband's cause.)
It is true
@Reyaj that many/most "quality" women seek marriage. This is how most traditional feminine women are raised. They get chosen early so the rest of the dating pool is leftovers or rejects to a degree. I do agree that some of these "good" women do end up back on the market after divorce, or even from being widowed. And the real quality women at any age are in enough demand that the women worth having as a "good" and "devoted" wife can find a man who will enter the marriage partnership if that is the aim. The trick is to pick the right woman if you are considering marriage.
You can have a life partner without marriage. I have friends like this who have been committed in a LTR for over 10 years. You must communicate your desire not to marry and find a woman who is agreeable to this. Also understand that without marriage end of life issues cannot automatically transfer to your GF. If you want a life partner outside marriage you need to specify legally and specifically how things will go in the event of your demise. While marriage has many legal liabilities in the view of the manosphere, there are legal benefits as well, especially as pertains to estate planning and parenting as some legally recognized examples where the law is supportive of the spousal status.
A good wife can absolutely add great value to her husband's life. The needs of a couple change over years together. Sex is more important during youth. Intimacy is built over time. Companionship and other non sexual values become far more important for elderly couples for example.
Not always true. A woman who marries makes her life harder in some ways, easier in others perhaps, but that is a matter of perspective.
My parents met in law school. Both have law degrees and both were working in the legal field when they married. My Dad wanted a full time wife and mother for his children. My mom honored his wishes and dropped her career (college educated, holding a law degree - not an inexpensive education) to be his wife and raise kids for the next 20 years. For 16 of those years she was out of the workforce at my father's request. My mother was capable of making 100K per year as an attorney or much more than that. Over her 16 years out of the workforce my mom gave up the ability to create 1.6 million in income that she could have made independent of my Dad. She also was out of the workforce during her peak income years (statistically speaking) and so missed these opportunities. Meanwhile she cared for the children (no day care or childcare costs incurred), entertained clients in the home, managed the bills, laundry, and household duties, and assisted my Dad at the office some once we all started in school. My mom is BPD nuts and eventually pushed my Dad away but all she got out of the divorce asset-wise was a house worth 195K. So one could make the argument that she actually got seriously financially shortchanged based on her giving up her income producing ability and prime income earning years in support of my father's career.
Many wives (good ones) do a great deal to support and encourage and facilitate the success of the husbands while giving up their own earning capacity and income potential to do so. That is the value I am talking about from a money perspective...never mind the value a stable home contributes to child rearing. There is a reason sites like SS advocate that you find a woman whose parents are still married. It is seen as an indicator of a stable upbringing and familiarity with more traditional male/female roles.
Marriage is about far more than sex upon demand. I can also tell you that having been the high earner and sole breadwinner in my own marriage for many years, the court will strip assets from the woman just as surely as the courts will strip assets from the man. The court seeks to divide assets with some equality, especially if there is a big income disparity between spouses. The high wage earner often gets stripped of some assets under the court's assertion that the high wage earner retains earning power, but that isn't always the man. Trust me I didn't like it any more than the guys on here but it is what it is.
Again you focus just on sex (very important I agree totally - however) You are skewed to a young man's view and do not see all the perspectives. Married people who are sick and have a spouse devoted to being their advocate and/or caregiver will tell you they are blessed to have someone to look after them and their care as they age or are infirm. Companionship is most important in the elderly years. My step mom of 30 years has been by my father's side as he has battled cancer, had strokes, dealt with all sorts of health issues; she is seeing about his needs at 78 years of age (despite her own cancer and health issues) and she continues to put my 80 year old Dad first and assist him as his life partner. She will be steadfast by his side until he dies. Then his estate will look after her (as will I and my siblings). As it should be. She has devoted her life to serve him as a great wife.
Marriage is about life partnership. In a partnership each partner brings value. Sex is but one piece of a much more complex puzzle for a marriage to last.
