You can't force someone to like you. That being said, just be nice, be yourself, and smile!
Hey, tell him you're interested.
At the end of the day, there's only so much waiting around and hoping you can do.
Sometimes your best bet is to tell the guy straight out that you're interested and ask him if he feels the same.
Whatever his response is, at least things will be out in the open and you can either move forward with the relationship or move on.
Someone like or don't like you! We can't do anything to make others to like us back.
If he's not interested in you, then anything you do around him is waste of time. Maybe stay friends if you could be fine with each other but if he's not interested in you in relationship manner. Then it's time for you to move on! And find someone who likes you back.
"Care for someone who cares about you"
And i'm sure that's how you deserve it! Instead of spending the rest of your life trying to make someone like you while they might never see you, and at the end you're the one who wasted your life. He's living happily and you just fallen behind. Instead of all that! You can move on and be your own lady with so much confident and independence and live your life happy till you find someone that belong to you and would like you naturally! Sure he will be there! Just you have to stop being obsessed with it. Then you'll meet him!
