Donna is right, and I'd add one thing. nobody warns you that dating sites depend so heavily on how often it goes somewhere.
I judge dating sites almost entirely on how often it goes somewhere now.
What decided it for me with dating sites were how often it goes somewhere.
If the everyday experience isn't sorted, dating sites will not go anywhere. You cannot really talk about dating sites without talking about how it handles day to day.
If you try best dating sites for open relationships, give it longer than you think you need.
For completeness, the ones people usually compare against on dating sites:
- turndate.site
- rendate.site
- datebie.online
That list is what gets mentioned, not what I would personally back for dating sites.
