What are signs a guy isn't interested in you?

1)When you call her she will be extremely quiet,or wouldn't ask any questions, or would make an excuse to hang up2)Whenever you two talk face to face she will look away3)Whenever you ask her to hangout or suggest that you two do something together, she'll say can I think about it or I am busy that day4)She is hesitant about giving her #5)She flirts but that's how she is with everyone6)She says she'll call but after about a week she still hasn't called7)She sees you and walks away8)She seems to be always listening to what you have to say9)She doesnt ask anything about you 10)You heard she's interested in someone else

This will change from person to person but I hope it helps...
