Started these dating apps for the first time in my mid 20s in a major metropolitan area

Made some matches. Did some banter and got one person's number for example.

Super receptive on the app and gave me her number, I called mid week supers short (she was with friends), then texted the next day. No response on the final text... Safe to say date today is a no show? I don't feel very motivated just going through the motions I suppose.

I guess my question is when should you just expect that its a ghost situation and when should you be that uhh go-getter dog character.

I personally don't enjoy the idea of contacting someone twice or more after no replies that feels like beggar behavior. That said this dating app dynamics is strange. Im always half expecting that my messages and presence is being drowned by 30 other guys at any given time so I haven't been stressing with slow replies but it does not instill confidence in me overall.
