Am I an idiot for still being friends with my ex?

He broke up with me 3 weeks ago. But wanted to remain friends but he barely responds to me unless he's at work and bored or has something to say about himself.

But when he's home he barely responds to me and even comes off cold in his responses if he does respond.

I'm just sick of it. I feel like he's getting all of the benefit and I am just left hoping that one day he will change his mind if I keep being friends with him. But I'm starting to think that's never going to happen.

I know I need to give up hope and move on but it's so hard letting go especially when the break up was so sudden.
