Love is not confined by age

[Xinfu]

Are they all correct?

-This is my boyfriend. He is older than me by three years. But love is not confined by age.
-Love knows no boundary regardless of age.
-Age does not decide love.

What would be the idiomatic English?

-Age does not decide love.

What would be the idiomatic English?

-This is my boyfriend. He's three years older than I am, but then age has nothing to do with love.
-When it comes to age, love knows no boundaries.
-Love isn't determined by one's age.

Just my opinion!
All three statements are true, by the way

Age doesn't matter when it comes to love.
Love is ageless. Love is timeless.
Love is blind to age.

There are many ways to say this.
