It sounds to me like in the past you may have "made promises" of being different, being nicer, changing, etc. and finally after hearing empty promise after empty promise, she doesn't believe you. NOW you are saying you've given up everything and you've changed...but actions speak louder than words, and she's heard your words before! So she doesn't believe you. As of yet, you have not given her reason to believe you: you've got MAYBE two weeks of "leaving her alone" vs. how many YEARS of promising and breaking your promise.
So I make a recommendation. Right now she will not hear a word you have to say, and honestly I would not tell her to listen to you either. Right now you need to have your ACTIONS match your words. Keep up with the counseling. Keep up with learning about her emotional needs and her love language but DO NOT BUG HER. Keep up with being open, honest, and sensitive.
Regarding your child, it is not reasonable for her to keep the child from you. From a legal point of view, you have just as much "right" to the child as she does, and if nothing else it's reasonable to have 50/50 time with the child. However, my guess is that she views your "parenting" as abuse, and if she can prove in a court of law that you were emotionally or verbally abusive to the child, or if she can claim that she or the child are afraid of you because you "threaten" them...then she can go for a restraining order and you would be ordered to stay 500 feet away from them both!!
Thus I suggest that you let her know that you deeply miss your child and want to spend time, but that you are sensitive to her concerns. Then make arrangements to have some third party present during time with your child--so that you could say something like "I know you are worried about the way I've acted toward <child> but I do miss <child> very much and as his/her parent I do legally have a right to parenting time. So what I did, to help allay your worries, is I've arranged for BOB or SUE to be in the house while <child> spends time so <child> will be perfectly safe."
