How do I parse this sentence?


> 君がかわいいってことには変わらないから安心して

I understand all the words I think but don't understand the grammar. What does
こと do here? Does it mean "The part of you that is cute"? Does 安心して mean be
calm or be at peace here? I can only understand it now as

> Because the cute things about you dont change, be at peace.




Here is how I would go about it.  
君がかわいい

> You are cute

ってこと

> The thing/fact

変わらない

> Does not change

安心して

> Don't worry.

君がかわいいってことには変わらないから安心して

> The fact that you are cute is not gonna change so don't worry.




The sentence sounds strange for me and I would prefer either of the following,
with a slight difference in nuance:

[code]

    君がかわいいってことには変わりがないから安心して
    
    There is no change to the fact that you are cute, so don't worry.
    
[/code]

or

[code]

    君がかわいいってことは変わらないから安心して
    
    The fact that you are cute does not change so don't worry.
    
[/code]
