G'morning! 

or G'night~

Today I will teach you to confess to someone in Portuguese!

Someone is in love here?

Ok, no need to tell me...

Well, first you need to go slowly so as not to scare the person. then you say:

   
I need to tell you something...
Eu preciso te contar algo...
   

Then you take all the courage in the world and says:

   
I like you!
Eu gosto de você!
   

Or if you feel something much stronger, you say:

   
I love you.
Eu amo você.
   

If you want to ask the person in dating:

   
You want to date me?
Você quer namorar comigo?
   

Or ask her/him to marry (invite me to the wedding if it works hahahaha)

   
Will you marry me?
Você quer casar comigo?
   

I hope you enjoyed 

And confess! There is nothing better than to declare someone!

Unless she/he does not match your love...

Is boring, is not it?

But you will never know if you do not try
