I've been wanting to write some threads about these topics, but I would imagine it might get a bit too controversial.
I think a lot of people, especially when older, get married on a whim and a prayer (literally) out of desperation to not be alone, only to wonder why things fall apart -- when there were plenty of red flags in the first place.
You mentioned medical issues and earning an income... That's a whole topic in itself. Over the years, there's been a pervasive general attitude that comes through the forum saying that women should not work, feminism has ruined society, and any woman who rebels against this (how dare she insist on earning money!) is an evil Jezebel -- no wonder she isn't married.
While I of course agree that a lot of feminism has been toxic, there has to be an allowance for reality -- people are getting married later, which means women need to work -- so what happens when they're used to having money of their own and are achieving their own goals?
I personally think one of the issues in the Christian dating world that no one is addressing is that men are burned out and no longer want to be providers -- particularly if it's not for a family they didn't seed themselves. But women, told by the church that men are to be providers, have images of tall, handsome men earning 6 figures who sweep them and their children (in the later stages of life,) off their feet.
But this is often not how reality works, and the church isn't talking about it. I think for as much as it's said that women have rebelled against the social norms of the church, men are clocking out as far as being expected to be providers.
One thing that's greatly surprised me as I've gotten older is that younger men (30's) ask me out. I'm very open about my age because I don't believe in catfishing anyone, whether online or in real life. When I ask them why they would be interested in an old hag, they've all told me the same thing -- it's because I pay for myself, I don't ask for money, and I don't have kids. I can also say that if you want to get a man's attention, offer to pay for HIS dinner as well as your own. If I got married, I would gladly sign a prenup because I don't want a man to think I'm using him for financial gain.
I've seen up close that men are tired of being seen as free dinners or potential secondary fallout parents. And in truth, a lot of women are hoping for a man who doesn't have kids -- but will accept theirs as his own -- leading to a very unbalanced system of expectations that obviously isn't resulting in happy, lasting marriages. And of course, I'm certainly not saying women are exclusive to this -- one of the reasons I left the dating sites is because men would expect me to immediately fall in love with being their free babysitter, never once asking about what I was interested in regarding a relationship.
And I'm certainly NOT saying that single parents are wrong in wanting someone to love and accept their children -- many of the people I know are part of blended families -- for myself, I've tried it once, and I'm hesitant to do so again. This might be my own flaw, but I would feel like the expectations in such a relationship were way beyond my capacity.
I think one of God's biggest miracles are blended families that love each each other and can get along. And I'm certainly not saying that there aren't people who aren't willing to take on other people's children -- but I also think people have to closely consider the expense and extra family dynamics (exes and other grandparents involved, etc.)
Then there is the other option, which is living life alone forever. When my then-husband left for his girlfriend, I was crushed because all my dreams revolved around him -- we wanted to have a family early, work hard, retire, and travel the world. All that seemed to walk out the door with him. But God told me I could still have that life in other ways.
And so I'm still working towards the original goal I always had -- retirement and travel, as are some of my single friends. We talk about traveling together. The children's agency I sponsor kids through has talked about arranging a group trip in which I and others could go meet our sponsored children.
But if a spouse came into the picture, how would that all blend together, especially if that person still had to work or had a lot of debts? Is the financially independent spouse now expected to go back to work to help clear out those debts? Most likely, as it would probably be necessary.
Will the retired spouse feel bitter about now being enslaved to someone else's debt? And how will money be split across the needs of kids, grandkids, aging parents and step-parents, etc.?
Across all ages and demographics, Christian or not, money is the number one reason for divorce, and it's easy to see why.
I have a few other thoughts... I'm going to write another post to make them easier to read, if anyone is still interested.
