Everytme we argue he gives me the silent treatmnt or smetmes he waits until it's dark thn kicks me out. why?

I'm 21 and his 62
We have been dating for 2 years
We have spoken about the future a lot
He has already kicked me twice
Everytime we argue he tells me pack my things and get out of his house
But this time he took me home
It Hurts because I love him so much
And he has hurt me so many times he recently took the house keys he gave me
Everytme we argue he gives me the silent treatmnt or smetmes he waits until it's dark thn kicks me out. why?
