Well I assume if you rejected him that means he likes you as well, so just tell him you made a mistake in rejecting him.
Meby you should try starting a convo with him
You can not get a boy to fancy you. If he doesn't like you, nothing you do can change that.
Your nervous. either you like him or your terrified of him.
Just be like: "Hey my friend gave me ur number and dared me to text you so...hey wuu2?" if you guys start a convo, great, if not, maybe get to know them a bit better or just txt hey occasionally.
Be yourself! They are only worth it if they fancy you when you are acting like yourself
You schoul let him know ASAP otherwise he will be in the dark. i know. i am a boy. teen, actually.
If a boy rejects you then he doesn't have any chemistry between himself and you and unfortunately you are going to have accept that and move on. If you chase him you will lose your self respect in his eyes and it will only put a further wedge between you. Start dating other boys and you just never know there is a slight possibility this boy who rejected you may look at you differently.
look amazing and talk to him
No.
There is no harm in going out with a boy who likes you, rest is your decision.
