How to get rid of my moms’s fiance?

Long story short - they are both almost 50. But this relationship is toxic: he uses her for money, calls her names I even think that he gets physical; he brainwashed het into thinking that her own family (parents and kids) doesn’t like her and that we are bad influence (he does that to control her- she never even picks up her phone around him; he is alcoholic. She was in abusive relationship before and divorced only because her ex wanted to.
i can easily pack his stuff and throw him out. But I know that she will run after him and never return.

To the ones thinking that is her business - no. It effects everyone around.
