My question is: You are over 45, and at this age, it seems more difficult than ever to find 'the one.'
I noticed that several people used the phrase "the one." I believe in A one rather than The one, meaning that there's more than one right person out there with whom you can spend your life.
While many here are happy to date around indefinitely, I'm one of those who would prefer a long-term, in-depth relationship because that's what I had before. I like the involvement, intimacy and dedication of commitment. If I can't find that, I intend to keep my life full, busy and rewarding without it. So, in answer to the questions, I have both a preference and an acceptance!
