Don't worry.He'll miss you.
You're the best he could get and he blew it. Don't let him make you think for a second that it was your fault. It's not. He screwed up,and you did absolutely nothing wrong.
You gave him your heart and you trusted him to keep it and protect it,but he couldn't.
And honestly he's not mature enough.
He's not smart enough. If he was smart,he would have cared for you with every fiber of his being and been with you in every spare second he could,but he didn't and now he's gone. But don't you cry. Don't call him telling him you miss him,don't message him,don't comment him,don't talk to him...just pretend like you don't care,because,well,you don't. And don't be surprised when he comes crawling back saying he made a mistake,and if you want to,go with him again,but make him work for you. Don't let him in the first time the doce bell rings,make him come back every day until you trust him enough. If he doesn't come back after a couple of tries,just let him go,but if he comes back every day then he's worth it,trust me. He's worth it!
That's all,thank you!
That's your day...enjoy it!
