No, is the simple answer to your question.
As you say, you maintained contact with your ex in the hope of getting back together. This is a common mistake which only serves to prolong the pain of the breakup, as you have experienced. The reason you feel horrible is because you are feeling the anguish of the breakup, all over again.
By asking him to block you, you were in effect giving him an ultimatum. You wanted to see if he would actually go through with it. Sadly, he didn't choose you. You also handed him control, by asking him to block you, instead of taking that step yourself.
One of the benefits of the no contact rule is that it stops this type of 'false hope' behavior. At least you've been honest with yourself, about why you kept in touch with your ex. Nonetheless, it is now time to forget about any chance if a reconciliation and move forward with your life.
