Help understanding sentence with と


From prologue of 義妹生活 novel

>
> ...ひとえに親父が「元気」だったから。よくもまああんな目に遭いながら再婚なんてする気になったと、心の底から尊敬する。物心ついたときから喧嘩ばかりの両親を見て育ってきた俺は、親父に離婚すると聞かされたときはそりゃそうだろうなと思ったし、自分の甲斐性の無さのせいだと頭を下げられたときは、いやいや母親の浮気が原因って知ってる
> **しと冷めた気持ちで聞いていた** 。

I understand that this し is reason marker and と is quotative but I struggle to
understand the rest of the sentence. I think this part can be rewritten as

> 自分の甲斐性の無さのせいだと頭を下げられたときは、「いやいや母親の浮気が原因って知ってる
> **し気にしないでくれ!」と言って、親父の言うことを冷めた気持ちで聞いていた。**

Is that right?

Edit:

Based on @EddieKal comments, it seems to me that という sometimes gets shortened
to と when placed before 気持ち. Does it apply to other nouns? What is the
difference between と and という in this context?




This is a quotative-と with implied **思って/考えながら** , etc. (But not 言って; you
cannot say something while listening...)

> いやいや母親の浮気が原因って知ってるしと冷めた気持ちで聞いていた。  
>  I was listening (to dad's apology) with a turned-off/sober mind, (secretly)
> thinking "No, I know it was because of my mother's cheating".

気にしないでくれ is not implied. He just _thought_ this. He doesn't seem to be willing
to support either of his parents anyway.
