Believe me, i really wanted to get some kind of revenge at the time, but i decided that the best kind of revenge is to do nothing and get on with my life and show him that i do not need him, Because when you hold your baby in your arms everything will seem complete and worth it, he will be the one left in the cold with nothing. Thats the best kind of revenge in my opinion
You havent done anything wrong!

If he wants to act like a tit, then let him. Who knows, he could just be scared, and needs a lot more time to get his head around it, a poor excuse, but it does happen.
If i were you, id just leave him for now, i wouldnt bother texting or calling him, If he does get in contact then you will see how involved he actually wants to be. The best revenge in this case, is to just ignore him, and get on with your life, and leave him wondering what your up too all the time heehee
Hope it goes ok
