You might want to consider Sequel. It’s a dating site that really focuses on quality connections for our demographic. I found this article
https://goodmenproject.com/...-for-people-over-50/ which gives a really thorough look at about it works. The security features are much stronger than on the free apps, and it really cuts down on the noise. It feels much more like a space built for adults rather than a game. I’ve had a great experience using it so far.
