No a guy just want be able to tell if you are on a period. Yes, some are able to tell by your behavior.
If a guy's talking to you on the phone, then he likes you. Period.
say you have cramps or stomach pains. they will know what it means
the regular signs of pregnancy, however you probably will not be able to tell before your next period is due. if you miss your next period that would be a big sign.
very good question, in all honesty there really is no set period of time:( I mean, I am a guy who just flat out tells a girl if I like her or not on the spot, yet the guy my friend likes had taken over a month to tell her that he liked her. So the time period varies ALOT. But don't get discouraged, if it doesn't work out just remember there are alot of other good guys out there in the world:)
Wait until you see him in passing period and talk to him in a quiet part of the school.
When he doesn't kiss you or hug you or hold you or cuddle with you. when he doesn't speak to you or talk to you about things for a long period of time.
if your a guy and your friend is a girl how can you tell if she is in love with you?
just tell him
He is .....into you
yes
I tell him that the guy I'm about to kiss is the guy who behaves and looks like you.
Honestly
