Most Helpful Guy
Give him space. From now on don't text him, only when its really necessary and even than not to abrasive.
Find yourself activities that makes you think less about him. When you text him: just send the message and put away your phone and don't check it in every minute; send the message and forget about it!
If you want to attract him, you have to make yourself harder to get. Love works in the opposite.
Believe me, don't show how much you want him, because you would look desperate and you will only push him away.
Just find any activity that isn't related to him and which makes you happy. Don't be sad because that's not attractive for a woman.
Hi will get suspicious about your sudden change and this way you'll make him interested in you.
Again, messaging him multiple times sound desperate so don't do that and anything else that looks desperate too! :)
(this all came in a brainstorm so it might look a little messy and raw, sorry)
