Don't assume you'll get back with him in the future because you have got back with in the past.
It often takes people more than one attempt to be free but that does not mean they don't succeed in the end.
Turn it around, if you got back with him, it's inevitable you'll split up again (so there's no point).
And you have an extra reason, your DD, not to go back.
You are better off without him and despite anything he may have said about you needing him, or deserving him, or not being able to do better, you will be just fine and dandy without him.
Limit his opportunitues to say anything to you at all. He does not define you. What he says about you and to you is bollocks. All of it.
If you feel this is too hard alone, get help- family, MN, read Lundy Bancroft, go to WA, do the Freedom Programme, keep posting here.
I have never yet read a thread where someone has said they were delighted they went back to an abusive ex. Many where people who thought the same as you, that it was inevitable, and then realised they were far stronger than they thought.
You can do this OP.
