Because this is such a personal topic for you, I hesitate to give any critical feedback, but I'll give it a shot. Just take it all with a grain of salt and only take from this what is useful to you.
Warning: I am very particular and opinionated about how words are used and about what is musical or poetic or not. I'm sure many people will disagree with my opinions, so keep that in mind, as well.
By the way, I am having trouble understanding just what you are trying to say. I didn't totally understand your opening explanation, and sometimes the lyrics lost me. It's a little confusing because, part of the time it sounds like you are saying YOU want her to let you go and part of the time it sounds like SHE wanted a clean break. I tend to be a little dense, so I am probably just not quite getting it.
So, not being exactly clear what you're after with the verses, I'm just addressing the chorus here. I hope I am understanding it correctly. This is your chorus as you wrote it:
Your anger won’t be eternal
Maybe you are already cooled down.
Do you ever wonder
If I would still feel like home to you?
Now, to me, this sounds like the singer is saying to his ex-girlfriend: "I know you won't be angry forever, and maybe you've already cooled off. Do you ever wonder what it would be like if we were still together?" If I got that wrong, my edits won't work for you. Anyway, this is what I did with your chorus:
I know you won't always be angry
And maybe you're already there
Do you ever wonder, like I do
If we would have made a good pair?
Just one idea and actually not the best, but it is pretty clear, I think, to understand.
Sorry I couldn't be more helpful. If I had more time, I would study what you wrote at more length and maybe get more good ideas. I hope someone else will be able to be more helpful.
