I'm with mjames interpretation of your words. What you miss is how he made you feel. How did he influence your perception of your surroundings when you were with him.
YOur heart is in the right place. YOu are full of love. And you know exactly the kind of love you want. Be thankful for the time you had him...not a lot of people get to have and know love like that.
Heartache is very difficult to overcome, but it can be done. And at risk of sounding like a walking cliche, I'll say it will take time. But you will overcome this as you'll overcome everything that comes your way.
Sorry to tell you, but you'll miss him for a very long time, and everytime you look at your baby's face, you'll see him there. And he'll come back to you...only thing is, you won't be at the same place he left you...so he might not find you.
Just hang in there.
