Tradução - Holandês-Inglês - Hallo schatje. Je bent echt de perfecte jongen...

Two minor things;

"je doet echt je best voor mij": "je best doen" means "giving it your best shot" or "doing your best" and not "doing the best"

"heel prettig" means "very nice", not "quite nice".

Dat is uniek maar heel prettig. needs to be re-translated.

Please give me another option to edit before we put it to a vote again.

Personally, I'd translate it this way:

Hello darling. You really are the perfect boy I've always been looking for. Now don't tell me you aren't perfect, because you áre perfect. You're always so sweet to me. You're really giving me your best shot. (You really do your best for me.) That's unique, but very nice.

Hope this helps!

DONE!

So lets vote!
