Interesting topic, and lots of good and diverse replies.
I'm a 44-year-old hetero lady, was married for 6 years from age 23 to 29, plus we dated nonstop and were engaged for 4 years before that. After my divorce, back when I was still cute and skinny and smart and funny, I went on a dating rampage -- not because I wanted to get married again, but because I wanted to see what I'd been missing out on, by being tied down during prime dating years. It was bunches of fun getting to know so many cool guys, but then I settled down dating two married men concurrently and one single one who lived 4000 miles away. Basically, I was making conscious choices to keep my single self here, free and clear. I mean, a married man can't move in with you, and can't actually demand anything of you. So I get to keep my house all to myself, do whatever I want, have company whenever I want, and for me, that's the best of all possible worlds. I'll never get married again, that's for sure. Being a wife just did not suit me. So, that's my happy choice.
Good luck with finding what works best for you!
