You said it was "her idea" but to do what? I meet people for lunch or activities plenty of times and it could be my idea but it doesn't mean I am going to be romantic with them. Is she looking for a relationship? Marriage? Kids? Or activity partner? Where have you met?

You had so many of identical stories. You are talking to strsngers online thinking it's friendship. You are talking to baristas thinking they are dating you. Etc it always ends up in disaster because those are neither friendships nor dating experiences. But few months later you do it again.

Did you already have a date? How did it go?
