Übersetzung - Türkisch-Englisch - hadi diyelim biri çok seni sevdi ...

I'd use simple present here.
"Let's suppose that someone loves you so much and gives you everything..."

Well, as it is an imaginary situation, I used "would". Should I change it?

That idea applies to an "if clause", but this is not one.

Oh, OK then!

Lily, you turned "..gives everything for you" into "gives everything to you", but this doesn't convey the correct meaning, I guess. (Or, am I wrong? )
"Giving all his/her -for example- possessions away for somebody" is meant to say there.

So, you mean: "gives everything away because of you"?

"Because of you" is better!
