So i had 3 dates in the past week or so. 2 Girls that were 8.5 or so that totally curbed me and one 7 that i dicked down on the first date. Can anyone tell me why it went well with the 7 and not the 8.5s

Date with 7: Meet at bar grab drink, make casual conversation and jokes. Changed venue after 1 drink since there was a fat bitch singing and we couldnt hear anything. 2nd bar we grab one more drink and make chit chat. As conversation is dying down a bit i grab the bill and suggest we get out of there (no physical escalation as of yet). As we exit the bar she gets closer to me and grabs my arm at which point i suggest to go back to hers and deal was done.

Date with 1st 8.5: Meet at izakaya, have one drink and app, makes jokes chit chat for about an hour or two and then i walk her to her car. Didnt attempt to kiss or physically escalate as she seemed to not be into it.

Date with 2nd 8.5: Meet at bar, have 2 drinks each make some pretty good conversation, better than the first two dates for sure, do some light kino on her arm, which she reciprocated. I get the cheque and we go for a long walk to her car. During the walk she kind of took me to a secluded short cut at which i thought it might be a good time to kiss, (she stopped and said the moon looks so nice tonight and kind of paused there). Like a pussy i didnt go for it and the walk ended with a hug and nice to meet you and thats it.

I have two theories. Either they are too high SMV for me and I need to improve my SMV somehow. Or because I didn't go for the kiss it was a turn off and they thought I'm too much of a pussy.

Thoughts?
