Confusion about meaning due to spacing and で particle


I'm playing a game and came across the following:

> 彼女が自然と人を惹きつけるのは  
>  きっと．．．．．．
>
> あなたの 誠実で大きな背中を見て  
>  育ったからなのでしょう。

For some reason I cannot understand the meaning of the second chunk due to the
space after 「あなたの」 and the で particle in 「誠実で大きな背中」

I want to read it as

> She attracts people naturally  
>  Certainly......
>
> Due to your... sincerity she looks at your big back and  
>  it's probably because she has grown up

Generally I have treated spaces like this as a slight pause. As if the person
it trying find the words to say. But in this case I'm very unsure as the
second sentence seems very wrong

So what is actually trying to be conveyed here or am I right?

Context:

There was a man who was known to be very honest and sincere. Him and his
daughter get into an argument one day. She ends up saying "I wish you were big
and cool! I hate you!". Unfortunately, soon after the man immediately dies
from an accident. He then becomes a ghost that takes a gigantic form

After defeating him in battle and before going to heaven, your party has a
conversation with him. His daughter is mentioned by one of your teammates. The
teammate says his daughter has many friends and lives her days in good health.
Then the teammate says the above




「背中を見て...」is an expression, and while it means _look at one's back_ literally,
it's used to mean _by someone's example_ metaphorically.

I'm assuming it has something to do with students who learn their master's
techniques by peeking over their shoulder, though I can't find any sources for
that claim. However, the Japanese Thesaurus clarifies [a similar
expression](https://thesaurus.weblio.jp/content/%E7%88%B6%E3%81%AE%E8%83%8C%E4%B8%AD%E3%82%92%E8%A6%8B%E3%81%A6%E8%82%B2%E3%81%A4):

> **「父の背中を見て育つ」**
>
> 子供が父親の物事に取り組む姿勢を見て、そこから学び大きくなること

All in all, I believe that passage boils down to meaning something along the
lines of:

> I'm sure she naturally attracts people, because she grew up to be sincere
> and great, just like you.

Albeit a bit more literary.

The particle で is, as Shurim said in the comments, a way to apply multiple
adjectives to a single noun.




あなたの, 誠実な and 大きな all modify 背中. The author may have wanted to prevent あなたの誠実
from being read as “your sincerity” with that space. It’s not a common
practice at all. And 誠実な背中 is not a very common combination. This may have
added to the confusion.
