Agreed. Usually there needs to be a physical attraction or something about that person turns you on to a high degree to even get there. For women these days it's not like the old times where you had to marry for financial stability or because someone's parents told you to. A woman can choose that partner on how she wants that partners to be for her.
I asked my friend if he said anything or did anything after that turned them off. Like it went well and they let you kiss/make out with them and then maybe you said something on text or in person after that changed their minds. Possibly they met someone else they had a stronger connection with and instead of just saying nice words they were going to be mean and just let you go so you never contact them again.
I understand if they never let you hold their hand or kiss them in any way from the start and from that you can gauge there is really no interest.
Some who are really attracted to you will even wait to kiss you since they may be conservative about it and do not want to come off easy until they get to know you better. I had this one girl a long time ago say she was attracted to me, took me to her favorite hang out spot that she went only with her girlfriends (she said I was the first and only guy she ever took there), she would sit closely next to me, grabbed and held my hand when we walked out. However, each time I went in for a kiss she would avoid it. She had 2 kids, was divorced and only been with 1-2 people her entire life. So I had to understand her perspective.
