I've been lurking for a while. I haven't been using Tinder lately since they decided to become shitty, but I got a new match that was easily a 7. Things were going okay until she implicitly invited me over for ice cream and Netflix, at which she became silent after I asked what her number was. What could I have done better?

Transcript:

Me: Hey, want to hear a cheesey tinder pickup line, or can we skip all that?

Her: Haha I mean I would say skip it but since you mentioned it I kinda wanna hear one

Me: If I flip a coin, what do you reckon my chances are of getting head?

Her: Haha well that was about a 4 lol

Me: Haha out of 5?

Her: Out of 7 haha

Me: Awesome! Seven is my lucky number. Could be yours too if you play your cards right, sweetheart.

Her: I just like the number 7 haha not quite sure why lol

Her: So how are you?

Me: Pretty good, just hanging. You?

Her: Same here. Watching some Netflix haha

Me: I can't watch Netflix without my best friends Ben and Jerry.

Her: Well then bring em over and lets watch

Me: What's your number?
