I don't get it :( how did he fall out of love so fast if it wasn't another girl?

He doesn't need to tell you if he's moved onto someone else it's not about him being "man enough."
He is the one that broke up with you it always tends to be easier to move on when that's the case as they knew it was coming and had time to prepare for it. It's harder for you because you were the one that got broken up with.
It's only been a month depending on how long your relationship was I doubt he is completely over you but he has no responsibility for you anymore and you can't get mad that he is 'turning his back on you' which he isn't doing by the way he just doesn't owe you anything and you have no right expecting him to.
Just take one day at a time and move on with your life I know it's hard and it takes time but you can do it and it gets better. If I was you I would avoid initiating any contact with him if he wants to talk to you he will, because he's the heart-breaker shall we say you shouldn't be 'chasing' after him so-to-speak, if he sees that you are doing okay without him and are not going out of your way to talk to him he is more likely to miss you and more likely to initiate contact and show interest in your life and In a couple of months time you can have the closure talk but until then stop talking to him it's going to hurt you a lot more then it hurts him.
