Here is a sure fire way to see if a girl likes you; ask her if she is married or has a boyfriend. If the answer is “no”, she may be lying but she is looking at you as a possible mate.
If she says “yes”, she may be lying but she don’t like you for sure.
When I ask that question, no matter what answer I get from the girl, I congratulate her and tell her that she is so lucky. I tell her that she is lucky to be all alone and independent or she is lucky in this day and time that a man would commit to her. Either way, its a mind fuck for her.
