I found the translation in wishbone's blog so credit to her.

Kuen nun/That night

Ta Thur Tong Kan Ja Dern Nee Pai Hai Hang
If you want to walk away from me.

Yak Dern Khon La Tang Tang Tae Nee Pai
You want to walk separate ways from now on.

Chan Mai Mee Hed Pol Ja Pai Rang Thur Ao Wai
I don't have any reason to hold you back.

Sud Tae Hua Jai Thur Tong Kan
It's up to your heart's desire.

Ta Thur Bok Gun Wa Thur Kid Leum Rueng Kao
If you tell me that you will forget all memories,

Yak Leum Rueng Khong Rao Mue Wan Waan
want to forget about us in our old days,

Chan Mai Krot Thur Leoy Tee Thur Pood Ma Yang Nun
I'm not angry for what you said.

Pen Krai Kaw Tam Yang Thur Chan Khao Jai
Anyone would do the same as you, I understand.

* Tae Ja Hai Chan Chue Dai Yang Rai Wa Kuen Nun Rao Mai Rak Gun
But how will you make me believe that we didn't love each other that night?

Saban... Thur Kla Saban Dai Mai
Swear... Can you dare to swear to me?

Man Aat Ja Pen Bang Kuen Tee Thur Yak Leum Man Hai Dai
It may be a night that you really want to forget.

Tae Hua Jai Kaw Roo Rao Rak Gun
But our hearts know that we love each other.

Ta Thur Tong Gan Ja Hai Chan Pai Hai Hang
If you want me to leave you,

Mai Yak Hen Na Gun Meun Tee Laew Ma
don't want to see me again as before,

Chan Kong Dai Tae Fung Took Kham Tee Thur Bok Ma
what I can do is just to listen to every word you say,

Tang Tee Mai Yak Dai Yin Leoy Sak Kham
although I don't want to hear even one word of it.

(repeat *)

Man Aat Ja Pen Bang Kuen Tee Thur Yak Leum Man Chua Kan
It may be a night that you really want to forget forever

Tae Saban Oh.. Took Yang Nai Keun Nun Chan Rak Thur
But I swear, oh... everything on that night, I love you.
