Yeah thats a certainty that he doesnt care im afraid. If he liked you he wouldve texted back by now and wouldnt have unfollowed you so willingly!
Signs a guy cares:
He makes sure youre ok, and will help you if not
He checks on you to see how youre feeling
He will take you out to places so you can have a great time
He will buy you things because he loves you
He will shower you with affection
He will stand up for you no matter what
He will take good care of you and treat you like a princess
He wont force you to do anything you dont want to
Things like that!
At least thats what id do anyway
