some more stuff that pop off my head:
-She says "it was nice meeting you" or when you feel she is saying a real "goodbye" - you can sense it in her voice.
-even worse - handshake, not even a hug.
-when you make future plans and she says "sure" (worse answer) or "i'm busy, buts we can text or talk about" or etc.
-she doesn't laugh or smile - when a girl is into you she will laugh from every sh1t you say.
-no eye contact, looking on other people while you talk to her .- this is probably the best indicator
-she offers to pay her part of the bill (but not in a polite way)
-she doesnt say thank you if you pay the bill.(this also indicates she is a h0e - probably goes on a date to get free stuff- and wants men paying for everything)
-radio silence, no telling anything on her side
-low pitched voice. no excitement about anything you do, or anything she says, short sentences.
-if you go to a restaurant or a bar, sit first on the chair, and look where she is willing to sit (if far away, no 2nd date)
-no flirting, its doesnt have to be sexuell on first date, but you should defintly flirt.
-she is not trying to touch you in anyway, or she avoids any contact. normally - they tell a story about something physical, and describing it by touching you.
-she doesn't drop hits on future meeting "i never tried thai food" "i've never been to that place"
-she had that thing she gotta do, or she orders the check her self just right after you're done eating or drinking.
-she goes too long to the bathroom , probably to check her phone.
-no text after date (she should text you it was a great night bla bla bla) - usually doesnt means it was a bad date, but that you SHOULDNT go on 2nd date because she would have texted you if it was a good one.
you can go on forever...
