When I was filling out applications, my older sister told me to lie about experience, and that they'd never check. I chose not to take that advice as I filled things out. Even though I was looking for my first job and my sister had been working for several years, so by default I knew she was more of an expert than I was. She would say the same thing to other family members, who also chose not to take her advice. In the end I chose not to lie, because regardless of location common sense tells you lying is wrong and people who have been lied to will react negatively upon finding that out. This isn't a cultural thing, it's true everywhere. And having lived in a certain country doesn't make you responsible for everything that happens here, either. Just like you could still give bad advice to a foreigner about some issue in France, and American can give bad advice about things here in America. Living in a country for a long time doesn't mean you are able to give good advice on any situation that occurs in that country. Human nature and the foibles of the advice giver still need to be taken into account.
You saw a benefit in lying, and so you lied. That's on you. He didn't put a gun to your head and make you do it. You allowed yourself to be convinced to do something you knew was wrong because you thought doing so would benefit you. And you know what makes a liar? The act of lying makes you a liar. The actions you choose to make define who you are as a person. If you don't want to be a liar, then stop lying going forward. Maybe you don't want to face that you've behaved as a liar, and it's easier to be mad at your husband and blame him than it is to admit you chose to lie and own it, deal with the consequences of your choice, and do better going forward. If you aren't getting any other similar jobs, it could be that type of job is screening applicants by degree, and you wouldn't have even been considered based on the truth. Programs screen by degrees and key words all the time before the applications ever reach a real person. I also think that if you called the job in an emotional state and sobbing that also may have had a negative impact, because it made you look unprofessional.
You have another choice going forward. You can choose to blame your husband and let this affect your marriage. Or you can choose to try and let it go and forgive and own the results of the actions you took. Forgiveness is also a choice, and an action. Just like lying is. You have agency.
