Tama si kabayang karerista, keep your questions as general as possible because i'm sure you're looking for a solution to a problem which confronts not only to a specific type of nationality.

Tackle the issue as mature people, give each other a chance. Reflect on yourself as well if you have done something wrong for your spouse to do such thing then seek a solution between the two of you to sort things out try to balance the good points in your relationship and not only the bad points whichever weighs most. Consider also your kids if there are when making decisions as they will be the ones who will be affected the most by this.
