It depends on who broke up with who along with the reason why you two broke up. As far as why he's ignoring there could also be multiple reasons why however he's most likely just moved on from the relationship. If he's ignoring you try to move on you deserve to be happy, and smile don't let this bring you down.

I'm sorry you broke up. Sometimes people say things they think you want to hear to pacify you until they can gain the distance to tell you what they really wanted to all along. I would try to accept that he doesn't want any contact with you and try to move on and work on feeling the best you can.
