Hi, Nancy,
There really can be love for couples in the middle-aged years, I know two people who did that. First, I have a friend whose husband died suddenly of a heart attack. It was crushing for her, but she managed to find a wonderful man she met at her church. They married and are extremely happy together. My mother and father divorced when I was in high school. She was a lonely forty-five-year-old divorcee—not exactly the type of woman men would race after. However, when I was in college, she met a super nice guy who worked in her building. She decided to pursue him and get to know him. They married a year later. So it’s quite possible that you can find Mr. Right somewhere around you.
I guess my point is that older people can find love. They can also find it without going to a dating site. Dating sites can work, if you go to one that specializes in your interests. One of my friends met her guy through a Christian dating site. They lived several hours away from each other, Skyped and sometimes got together, then married a year after they met. My brother got a divorce from his wife and met his current wife on a dating site. So not all dating sites are for hookups, nor are all people who go to them interested in a hookup.
As for what you will need to do: Make sure you specify that you are looking for a serious relationship ONLY. It wouldn’t hurt to mention that they should not bother contacting you if they are interested in a hook-up. While some people won’t abide by your requests, I believe that some will. You will have to carefully weed out the ones who aren’t serious. There are sites out there that seem to be for hookups and nothing more you want to avoid those.
Although I’m married, if I were looking for a nice guy who would provide me with a true relationship I’d go to a site like Christian Mingle. If you’re not religious, Google non-hookup dating sites. I just perused the Internet and found a few. Good luck!
