My husband’s brother harasses me, should I tell him?

The title sums it up. My brother in law was friendly at first, then he started throwing weird comments left and right. Then it was plain harassment. He would say weird things to me and he even physically attacked me. That was the most disgusting thing i ever had to face. The problem is we live in their family house and its divided but i never feel safe when he is around. My husband has absolutely no clue and it gets weird when he asks him to pick me up or something cause i never want to be alone with him. Now i feel like i need to tell my husband but that absolutely terrifies me, there are a lot of factors in this. They are brothers and i don’t want to feel like i am separating brothers even if its on him. I don’t want to make my husband sad. And second i am actually scared for him, my husband will absolutely not take this news well and i am afraid of the actions he might take. I don’t want to ever experience his anger even if not at me it just terrifies me; I don’t want him in jail and that’s not a sight i want to see. I have been asking him to move out but its not easy and i don’t know what else i can do to end this without wrecking havoc in the house.
