Police officer husband

You are a serial killer. You have a husband, Andrew. Andrew worked for the police, solving the most difficult cases. He spent most of his time at work, but he didn't forget to spend time with you, thinking you were a fragile and innocent young man. He tried to protect you from everything. But there was one case he couldn't solve for a long time, namely a series of murders. You were the criminal who committed these murders. You were meticulous, never leaving any traces or clues. Nothing. Andrew spent all day at work, returning late and not suspecting that the killer was you. One time he came home late again and caught you chopping vegetables.
