Help !!

Vanessa • 15 years old 😇 happily with the love of my life 💏💑
My hubby lied to me about a gun that he has . At first he told me that it was real and when I asked him to get rid of it he told me it was fake and that he was messing with me and I believed him. But I just discovers that it's real . How do I confront him about that ?????
Keep in mind :
He's 17 
He got it illegally
