Maybe you can move forward without looking at the past, you cant decide this for your daughter though. You may have spent a long time looking at the past, maybe she is still struggling through it.
Or maybe she has problems in life, work, love, etc. Or maybe she is just rash and bad tempered. Or just family dynamics. Me and my sister often disagree, and she has one row after another with our dad. She is just volatile. I dont bother anymore, just wait till it blows over, it mostly does. My dad does the same for an easy life. She is too old to expect her to change her behaviour. She wont. She does not see anything wrong.
(Like today, she came back from town, left her shopping in the car, the car in the garage, across the yard, 10 meters on wet ice. Said to me, I left my shopping in the car. Can either of you go get it. I said I can do it later when I go out. She replied "but my bread for my lunch is in the car". I told her there was bread in the freezer and she mumbled "oh fine then, I will just eat bread that is too brown for my stomach to handle and I will just end up feeling unwell". I left her to it. If she has chosen to leave her lunch in the car she cant just say skip, and we all jump across an icy yard to get her bread out. My dh eventually left when he had an errand in the garage. She promptly asked him to go back to the car to check he closed the boot properly as she trusts nobody but herself to close it properly, and we all know how easily the battery of her car drains.
My point is, we all have unreasonable siblings, children, parents, etc. At some point we just give up trying to deal with them, or raise them, or point out the error of their ways, because it will lead to more grief than its worth. It is disappointing to see that your sibling/child/parent is unreasonable, but sometimes you just cant change how they behave only how you react to it.)
You are asking what you can do in future. I dont know how anybody can decide this as it also relates to another person and their behaviour. I guess you can continue as you are (seems you are doing well with love, olive branches and reaching out to her), so not sure what else you can do in terms of yourself. The rest is up to her, is it not?
