I think signs of a teen crush are pretty obvious....If it is a crush...then you would probably be shy and maybe red faced around the person... u care what that person thinks of you, and if you even question if you have a crush on someone, then you probably do. You definatly know when you dont have a crush on someone, so if you question it....u probably do have a crush on that person
can't look into his/her eyes, feeling shy whenever he/she is around, love to stare at him/her from afar, feeling happy whenever you see him/her.
blushing
you start to flirt
Flirting, blushing, touching you more often
He will pay attention to you, go out of his way to see or speak to you or even do things for you.
Instead of looking for signs that your crush has a girlfriend or not why dont you just ask him. He can only say yes or no. Either way its a win win situation. If he does then it lets you move on and think well he was not worth it. If he does not then it gives you the opportunity so strike up a conversation and ask him out on a date. I hope this helps you.
I'd say see how he is acting around a certain girl. I'm sorry but That's all I can help you with.
Show him/her signs that you have feelings towards him/her.
Just walk by him and see if he watches you get to point A to point B.
If he shows other signs that he likes you he probably likes you.
ask her in a round of truth or dare.or watch for signs ,see watches him,she talks 2 or about him.or u could straight up ask her.
some signs are acting werid around the one they like, sweaty palms, drooling maybe, butterflys, romantic music in your head, maybe even slow motion walking!
You should show signs that you like him (flirt), and then if he shows you signs that he likes you back, then that means he must be interested.
She doesn't have to admit that she likes you or anyone even if you think you see her giving off the so-called signs. These signs can be inaccurate. They're not always a surefire way of finding out if she likes someone. Leave the poor girl alone. Harassing her to admit a crush will likely make any crush she did have on you alone. If she wants to go out with you, she might say something about it.
