I am a little confused, from all your previous posts you were saying you wanted out, you wanted to end things.
That he wasn't giving you what you needed, and that he was emotionally abusive.

Then he broke up with you, which seemed like the answer to all your questions about if he wanted to commit...obviously not.
Did you then realise that actually you did want to be with him even if he didn't want any of the things you wanted?

You want him back. In what way did he do or say things to make you feel loved, wanted and needed?
What way was he providing you with what you needed in a relationship?

What will you be getting back, that you need so badly from him, should he come back?

Whatever happens I wish you all the best.
