boy doesn't like me back

Hey looking for some advice,
So I really really like this boy and I have done for about 5/6 weeks, I've kissed him on 2 nights out and we were talking flat out, and now he's been very distant and taking a long tim to reply and I think he doesn't like me anymore, I understand that there's nothing I can do to make him like me, but how can I get over him and stop liking him? Thanks xx
