Husband and wife are partners and they have to share everything in their life. So, it’s completely okay for you to ask your wife to help you with the finances if she is capable of it. As you have recently lost your job so it’s obvious that you have to depend on her for the time being but you can’t make it a habit. Your wife helping with your finances is nothing to be ashamed of but you can’t depend on her for the rest of your life. You both have to share equal responsibilities. But you can definitely take her financial help until you get a new job.
