"Saya sangat gembira bertemu dengan kamu"
Because they are happy too see you again if they really like you!
Jumpa lagi - see you again Selamat malam - good night
Je suis si content(e) de vous revoir
I am happy to see you = Eu sou tu feliz te ver
It means exactly what it says. The other person told you that because they were happy to see you again - usually said after it has been a while since the last time they saw you. Sometimes though people will just say that to be nice... etiquette, you might say.
when am I going to see you again = Cuándo voy a verte de nuevo
Sigmund Freud believed dreams were often wish fulfilment. In this case it would mean you wish the person was still alive.
