She sounds awful. What a loser. Terrible.

The only thing I’d suggest is to avoid sharing intimate details of your life with people you barely know. The only person who knows details of my sex life is my husband lol I’d not want to know what happens in a bedroom of even my closest friends, why would they need to know mine? No one can spread details of your marriage if they don’t know those details, and they shouldn’t know. It’s private

That’s quite strange that you want to share that with random person in a meetup group. Same about meds you take. Why would she need to know? I am not saying you must be secretive but why does everyone need to know?

I’d try to be more selective about what you share and when and why and with whom. Take your time to become close friends before disclosing too much. And some stuff like your sex life doesn’t need to be disclosed at all
