Hope to move forward?

Dday was 7 months ago, and recently I’ve come to realize my treatment towards wp has been not the greatest. He has been doing everything right and I was still so angry all the time and taking it out on him. I’m changing, I feel like I’ve been doing better, I’ve chosen to move forward and let all of it go (obviously without forgetting/rug sweeping). i’ve been much nicer to him but my past behavior has caused him to feel slight resentment. he is still committed but isn’t sure everything will work out. There is pain from both sides. Just want some advice from others who have been in this situation? Were you able to move forward and truly let things go together? Is there hope?
