I agree with Breaking Dawn, give her space.

If you acknowledge being "the cause of most of it" and having been "a bit abusive", then she needs time. She needs time to sort out her emotional wounds. So, let her breathe.

And I would work on your personal issues so that there is no repeat (e.g. abuse, toxic relationship, being the cause of the upset etc.) IF she were to give you another chance. Even if she did not come back to you, it would help you in other relationships, so you don't repeat the same pattern of behaviour with other partners.
