I imagine “open relationship” means both parties are allowed to see other people or maybe something between “serious relationship” and “friendship”.
Having said that, this website was created because between the years 2020 and 2021 it was always welcome to meet a person who knew what was going on and the primary reason for this website is to help find people to talk on the same wavelength as yourself.
For example, if I meet a person who had COVID vaccines, I won’t talk about vaccine adverse events and all the topics related to that. If I meet an unvaccinated person, we can talk about a wider range of topics.
