I need help now please?

okay so me and my boyfriend live about five minutes away and he can drive. he's always joking that he will kidnap me one day, but i'm really scared he will. i have no problem with that because i trust him, but i live in a hoarder house. it's not me, but my family and that's the reason why i've never invited him over or anybody at all. what do i do? what if he finds out the secret i've always kept being my own home???? how do i keep him away???
