I went on a 'first date' with a girl from Tinder this past Saturday. Got some coffee and went for a walk around the city and the parks. Conversation was good, had kino and she seemed really into the eye contact.

She texted me that same evening, thanking me for the coffee and suggesting we go see a concert.

I replied on Monday, letting her know about some local shows...they started fairly late so I suggested she could otherwise come round for dinner. Looks like she's read the message, but hasn't replied. It's only been 24 hours, but should I send a follow up text, keep waiting or take this as a sign of disinterest?

I guess she could just be busy, but in my experience, when the girl initiates texting after the date, let alone suggest another meetup, she's definitely interested. EDIT: If it helps, she's 20, I'm 22.

UPDATE: So she replied just now with the following: "I won't be able to do this weekend but if there's anything up next week that would be great :)"

What do you make of that? And I intend to avoid replying for now.
