You need to decide your priorities first. You need to decide what is more important to you. Then have an effective communication with your wife. Try to ask her why she doesn’t want to go abroad. As you are getting an amazing job that means it won’t only benefit you but her too, then why she is denying to go abroad? And divorce is a very big step to take and she needs to give you a proper reason for saying this. Some people don’t want to go abroad because they think they won’t fit in there and some fear that they won’t be able to meet their family very often. So, you need to talk to her and try to find a reason for her denial.
