My fiancée doesn't want me to work abroad

I’m a former IT engineer in my 30s, while my fiancée is in her 20s and is attending a vocational training program.

I have been unemployed for half a year after being laid off earlier this year, and I couldn’t find a suitable job until recently, probably because of the large labor pool and my non-outstanding professional skills.

I received an attractive offer from a company a couple of days ago, which requires me to work abroad for at least a year. I asked my fiancée when I applied to this vacancy whether she would be fine if I were to work abroad, to which she replied that she would be glad since I could earn more money to better prepare for our future.

But when I informed her that I got the offer and would have to leave in two weeks, she cried a lot, begged me to stay in Vietnam, and told me to find another vacancy with a lower salary. She said she wanted to have me by her side, even if that meant we would have to be tight on our budget.

On the one hand, I do not want to be separated from her either. On the other hand, I know I could not find any job as good as this in Vietnam. I suggested that she could go abroad with me, but she didn't want to do so. We argued and she has ignored me ever since because of this.

What should I do?
