nurse a snake in (one's) bosom
To befriend, look after, or take care of someone who proves to be traitorous, untrustworthy, deceitful, or ungrateful. I thought the profligate had seen the light and was seeking redemption, and so I took him into my care. But before long, I knew I had nursed a snake in my bosom, as I awoke one morning to find myself robbed blind! I thought our love was not only mutual but indestructible; and yet, I have nursed a snake in my bosom all these years: my darling husband has cast me out and run off with a younger woman.
