I love her but she's a thief

I love my wife and she's everything I've ever looked for in a woman but recently I discovered that she's a thief.

We've been having issues of money disappearing and she kept on insisting that it could be the maid or the relatives who frequent our home.

Not until I caught her red-handed going through my wallet. At first I thought she trying to find out whether I was cheating as women do but I later realised that my money was less by shs 60, 000.

When I confronted her, she denied and I let it go for the sake of our rlationship

However, I realised that it's a bigger problem that needs an urgent solution when my sister visited and lost her over sh300,000 at our home.

I knew it's my wife but I wouldn't dare mention a thing.

What do I do, will she ever overcome the vice?
