No, you're not being stubborn or rude, but you have to accept that this is her decision. The issues that you described are serious, those wounds are deep and do not heal easily.

Let her know that you love her, and that you realize that it may be too late, but you realize how very wrong you were and you're working on those issues, not for her, but to make yourself a better person.

Whatever you do, don't PUSH. Let her decide what she's ready for.
