Perhaps you can send an email/letter that you can translate into Malay. [http:free-translator.imtranslator.net/] Dear Xvvv, I have to tell you that you have really hurt me when you said/did [ insert the facts here] I just can't forgive you for what you did. Maybe one day I will, but at present I am still angry. Please don't attempt to contact me in any way. Emjahay.

If you mean to say it in Malay, you can say "Saya tidak pernah menyesal untuk merasai apa yang saya rasakan sekarang or you can say "Saya tidak pernah rasa bersalah untuk mengalami perasaan seperti ini"

thanks but that does not help me at all

just tell the one/s involved: "go to hell and find something useful to do there"
