It means that you are not in a relationship any more. That's pretty standard. When people break up and say they 'still want to be friends', they don't mean talk every day and hang out and act like you would with a 'regular' friend. It means slowly drift apart amicably instead of ending it with a big fight, and act civil with one another if we randomly encounter each other at a party or in a store or something.
If it doesn't work that way, it just ends up hurting the person that still has 'feelings' a lot more in the long run. This can help them get over it, by helping them give up on the 'glimmer of hope' that a lot of people cling to, as it really delays the healing process and makes it hard to get over a person.

It's his choice and business as you're not his girlfriend anymore. Maybe he met someone new or is not interested in being casual friends with his ex. I think people say let's stay friends but it doesn't always work out well.
