thank you so much! And one more thing

do you think if I call the police, he will get worse or not?
I mean, i still hope he can change and we get better and better after understanding each other.
But I also heard that some one else recommend that if the domestic conflict was interfered by others, or even by police or special group, things will get worse and no hope to recover.
How could I do in order to not only protect my self and but also keep hope.
Thank you soooooooooooo much!!!!!!!!!!!!!!!!
