If he takes a day to text me back, should I just forget about him?

It takes him hours to text back and sometimes the next day. He says he is busy and 'doesn't sit watching his phone'. Guys, why does it take you so long to text back? Should I just assume he doesn't really like me?

Really? He doesn't want to seem to eager? It's so annoying. How can I get him to reply sooner?
