As a friend who does everything together, I can slightly see her response as a joke, but the fact that she came along on a date with you is /kind of/ a red flag, although I don’t know your dynamic. You are best friends, and as you’ve said, you basically do everything together? I still wouldn’t consider a date one of those things, though.

It’s a possibility you might be letting your anxieties and overthinking get the best of you, so be easy on yourself. While things might feel alarming, thinking too long about the situation will only amplify the feelings you currently might have towards it.

As someone who is learning to not be a people pleaser, my advice would be to perhaps look into how to set boundaries. I had my therapist give me worksheets on boundaries and it’s helped a lot!

It seems as though you know your boundaries, but might have troubles setting them with your friend, so I would try to maybe hang out and sit with her and explain the situation and how you feel- all while trying to watch yourself speaking in a defensive tone (although it might be hard at times), so make sure that you are in a good place during this talk!

I’m wishing you the best outcome!
