Can my girlfriend force her husband out of their home?

My girlfriend wants a divorce. She is bringing in the only income and her husband is freeloading. She would like to divorce, but, in a dispute where she called the police, the husband was the one who was supported and she was told in effect that she had no grounds. Her husband was being abusive at that time. He told the officers that "she's only called you because her girlfriend told her to." The police officers did not ask for any kind of show of bruising or take her complaint seriously. She would like the husband evicted from the house but does not know how to go about it. Can she kick her husband out of their home?
