Billie Eilish - Happier Than Ever Lyrics Meaning

I think that she lived through a hellish period of a toxic relationship, and she reflected her experience in this unique song and found the appropriate melodies to express the difficulties she went through.
I keep this song on my phone and I don't even think about getting rid of it.
Every melody, every rhythm, every word expresses the bad relationship she was in. If you notice at the beginning of the song how calm and stable her tone of voice is, as if she is maintaining her mood or something like that, after a few seconds the tone turned sharp, and it seems as if she is revolting, so she is angry, upset and sad, because she is tired of continuing her relationship with him.
In the tone of her angry revolutionary voice, there was some sadness, a lot of blame, and a touch of despair .
"When I'm away from you, I'm happier than ever" : she feels happier when she s away from him coz he s toxic
"Wish I could explain it better" : she feels so happy till she can't find better words to describe it .
"Give me a day or two to think of something clever
To write myself a letter
To tell me what to do" : she will give more time to herself coz he seemed like an energy vampier and coz she felt like she gave him more time than he ever deserved.
"Do you read my interviews?
Or do you skip my avenue?" : he is not treating her right , he seemed like he really don't give a shit about her , so she kept asking to show how shitty he is .
"When you said you were passing through
Was I even on your way?" : she ask if he see her as the chosen one or the women he wants , she ask him if she is enough for him .
"I knew when I asked you to be cool about what I was telling you" : she knew alot of things when she asked him to be cool , maybe coz he was stressing her out or didn't trust her while she was trying to show him something .
"You'd do the opposite of what you said you'd do and I'd end up more afraid" : as i said .
"Don't say it isn't fair
You clearly weren't aware that you made me miserable" : this explains what i just said .
"You call me again, drunk in your Benz
Driving home under the influence
You scared me to death, but I'm wasting my breath
'Cause you only listen to your fucking friends" : *tch* what a shitty bf .
He scared her but she said that she s just wasting her breath which means that he don't listen to her words or mind her at all coz he was listening to his fucking friends instead of listening to her , which break her trust in him .
"I don't relate to you
I don't relate to you, no" : billie is reassuring .
"'Cause I'd never treat me this shitty
You made me hate this city"
-------
"And I don't talk shit about you on the internet
Never told anyone anything bad" : she thought he s the best for her , she wanted to keep his picture clean .
"'Cause that shit's embarrassing, you were my everything" she feels so embarrassed about the way he was treating her .

I did not complete the translation of the rest of the words because the meanings are clear. This song is full of meanings and feelings and deserves to be heard by the whole world. This song is perfect for me .
