She Was Miles Away

Hello everyone,

Could you please tell me what "she was miles away" means in the following patagraph?

"I think you're right, Biddy." I said sadly, but I love her so much."

I was very upset and started to cry. Biddy put her arm gently around me.

After a while, I stopped crying and Biddy said, "Thank you for telling me, Pip."

I thought then, that I could fall in love with Biddy, I would be a happy man. But I knew I could not - I could only think of Estella, although she was miles away.

I know that this sentence has two different meanings, which are:

1. She was miles away.

It means that she (Estella) was far from Pip (because Estella was in France learning to be a lady) when he was telling his story to Biddy

The above interpretation was literal.

2. She was miles away.

Be miles away is an idiom. According to Longman Dictionary, it means "to not be paying attention to anything that is happening around you". In light of this, it means

She wasn't paying attention to the love Pip had for her.

In the novel, Estella is usually rude to Pip, but Pip loves her so much.

P.S. I go for the latter one.????????

Regards,

Joseph
