I'm not sure what your experience is, but I have noticed that couples only like to talk to other couples. Our so called "friends" treat us like we are diseased and avoid us like the plague, especially once they get married and have kids. At that point, if you can't talk about couples and parenting stuff then you are a worthless to them.
Ditto the thought. ?
I mean you barely know this person, you met them last week and they are somehow already your "soulmate". Bizzare. No wonder so many marriages end in divorce. It takes years to learn the ins and outs of another person, not a week.
I like that you call dating a "culturally ritualized" practice. It is somehow so ingrained into our society that if we don't date then we are somehow broken, or worse "hiding something". It used to be that people married for non-romantic reasons, but now nobody seems to do that anymore. Romance and sex are everything, and as has been noted, it is difficult in our society to have one without the other.
