I find it strange when a date went really well and I like the girl, she doesn't turn up for a second date or at least makes it hard to schedule one (gives excuses not to meet).

But sometimes I'm not too keen on the girl, messed up a few times and failed shit tests, she is still consistently turning up for dates week after week to do boring shit with me. Zero resistance and always down to meet.

What's going on here?

Example:

Girl A. First date was like 5 hours. We hit off so well, and I brought her to cool places she later said she was really impressed by. We share similar interests and have a ton of fun. I get the IOIs and escalate. We are intimate by the end of the date, all goes well. We text after talking about how we should hang out soon. Now after that, she ends up cancelling on dates because she's stuck at work and doesn't offer to reschedule. I simply can't think of where I messed up and why she's hesitant on another date.

Girl B. Now this other girl I've met, I'm barely interested in her. I probably failed every shit test because I don't even want to fuck her. We didn't hit off too well on the first date. She barely asks about my life. Zero IOIs from her. Dragged it on for way too long and it got boring. Awkward meaningless questions to fill the void. We don't even have similar interests. Absolutely should've gotten out of there. I kept asking for a next date anyway because she never cancels. It never got much better. Sounds bad right? No. She turns up every single time for my unexciting dates. Eventually I have to soft next because our dates are just tiring.
