@Alameda:
I can see the appeal of sex on tap and some company sometimes but any relationship like that so quickly feels cloying and scary. They start off all normal and nice but then want to know where you are every three minutes.
That's not normal, wanting to know where you are every three minutes. You seem to have an unfortunate talent of getting into abusive relationships.
That said, maybe it is normal and the happy couples I know are exceptions rather than the norm. You never know.
I tend to be against marriage because, while the people I know seem to be rather happy in their marriages, and I grew up happily in a nuclear family, I also know of many, many, many people for whom marriage and nuclear family is a prison wherein they are isolated from the rest of the world, and horrible things can happen.
My advice for young girls is to get married to their female best friend for the tax benefits (if your country has legalized same sex marriage and married couples get all those nice tax exemptions), and have men in their lives only as visitors. Safer that way if a man turns out to be abusive, and also the hassle with who does how many chores is not as bad with female roommates on average.
Second best thing: Not marry at all and share housing with other women.
Third best thing: Live alone.
After that come all the models where there's a man in the house.
Now, of course safety also depends on whether you have good self-esteem and are able to detect abusive men early on, but if I look at reality, many women don't seem to have that, so it is kind of stupid to advertise marriage as standard.
If you want to make a general statement on what is best for people, then marriage is not so recommendable.
