Khaleesi I found Tinder (and the other dating apps) a bit like that, to be honest. I found that either chat turned to sexting really early on, or it kind of dried up. I found I had to be quite active with sending first messages and/or making sure that I replied to people in a timely manner, and always with a question or something like that, so there had to be an answer, if that makes sense.
Funnily enough, the guy I am actually seeing now messaged me about a common interest that we shared (music). We exchanged a few nice messages, in which he told me about a radio show he thought I might like, based on my profile. I listened to it and messaged him to say I had enjoyed it, and then I didn't hear from him for a week, when I messaged him to say I'd put the radio on to listen to it again, and it all just went from there 
On that front, I had a chat with Mr Teacher (the guy from the anecdote above) last night about things, and we are both on the same page in terms of seeing each other exclusively and seeing where things go
