If he didn't like you he probably would have said no. But the fact that he didn't say no may be a good sign. However, just from this I can tell that he is tired of being asked about it and people need to stop. Because if they don't stop asking, chances are they will ruin any possible relationship with him for you.
That guy may see you as his 'someone special' but maybe he's not sure if you see him the same way and he's scared how would you take it if people ask u about u and him dating and ur not and if his friends ask him that DAT means he likes you and may have told his frnds and they wanna know if he won ur heart or not. Hope I'm helpful.💜.
