I had a relationship with our house help and helped her build a home, which she promised to repay. Now, she’s refusing and threatens to tell my wife, which she’s already done. My wife is devastated and threatens to end her life. I’m a government employee and don’t know what to do.

Your situation is complex and you should seek legal advice immediately. It is unclear if you have any legal recourse to recover the money, and your actions could be construed as an extramarital affair, potentially affecting your employment. Your wife’s emotional distress is also a serious concern and you should seek professional help for both of you.
