So i have been talking to a girl every day for about a month and I really really like her. We’ve been getting on really well and I’m pretty sure that feeling is mutual. We’re going on our third date this weekend and I want to talk about dating exclusively afterwards, but I’m not sure if it’s too soon. I’ve personally made it clear that I’m not dating anyone else, but she has not said the same. She’s leaving for school next month and I want to talk about it before she goes, but I don’t want to pressure her too soon.

TLDR how soon is too soon to ask for dating exclusively?
