Dating doubts .. hehe 😅

Hi people...

So I randomly happened to meet this person as we work in the same city. We exchanged numbers, started talking, met a few times too.

Things went well until the person asked, I hope you are not looking for something serious. We are. Just friends.

Well fine. I may be thinking of taking serious, atleast somewhere at the back of my head. I find casual relationship a waste of time..

But I didn't even bother to confirm whether we were officially dating. Should I ask it directly.

I'm worried how they're gonna react . Plus it's clear anyway that they're not serious. So should I take it ahead as a friendship only.

And is it fine to ask if they are open to me dating other people then, or is this implicit?

Your advice helps, please share thoughts 🙏
