If he has asked for your number you should wait for his text or call. Do not text him first.
I don't think you should wait any time at all, just text him back.
i would wait..if you really like him you should wait because you should make sure he likes you too. don't worry he will text you back hopefully.I would text him, but it depends on your personality. if youre bubbly and flirty, then its normal to text him more than once, BUT DONT BE ANNOYING ABOUT IT! dont constantly text him. if youre more laid back, i think you should wait. if its been more than a few days, maybe you should text him, but just once. never know, he may not have gotten it.
Wait on her to text you back, and not be paranoid.
Usually it's good to let him text you first...but there's nothing wrong with texting him first. Just keep it casual :) Text him first. Guys will wait for you to text them. Sometimes they will write you first but if you never write them first they'll just assume you don't like them and will lose interest. If he doesn't seem to responsive though, then there's not much hope. But wait and you run the risk of losing to the girl that does write him first.
you should ask and wait for an answer
this is an addition from the top but im wondering if i should keep texting him first or wait for him to text me.. and how long do i wait?
No, girls LOVE it when you text them first. But do not say something like Sup, or short one word texts. Make it more interesting by sending longer texts.
wait for her. its annoying when ppl repeat their messages
text back asap!
if you really like them, just text him/her.
Give him 2 days
