麻烦大家帮帮忙把这段话翻译成英文，我的未婚夫要生日了，我想写在贺卡送给他

I’ll never give up on you until the moment I am desperate and the second you say by yourself that you don't love me.

I will be with you forever untill the desperation occurs me, untill you say you don't love me any more by yourself.

我的未婚夫要生日了，我想写在贺卡送给他:我永远都不会放弃你，直到我绝望那一刻，直到你亲口说你不爱我那一秒-----
My fiance to a birthday, I wanted to write in the cards given to him: I will never abandon you until I despair of that moment, until you say you personally do not like my second

I will never give you up until the moment that I am disappointed, until the moment that you yourself tell me you don't love me.

HI
This is my personal translation for you

I'll never leave you alone but when you saying that " I hate you" makes disappointed.

Hoping to help you.

I can not abandon you forever all, until I am despaired that moment, you do not love me until you speak personally that one second
