<human>: My best friend, Amelia, has been in an abusive relationship for a while now. 

She lives across the country, and not too long ago things seemed to hit the fan with the abuse and the police got involved. He was charged by the state and I won't get into the details unless necessary but they were only recently allowed to legally see one another. Right now, they are both living in a property that she purchased.

She called me yesterday very distraught. She wants to break up, and he refuses to leave her home. The obvious answer here is to call the police, I know. But she doesn't see this as an option, since he will go straight to prison for a very long time. Unless she is in serious danger, this is not an option for me either. It is very important to me that I am there for her in the best way possible and I don't feel that the emotional turmoil I would cause for her would be fair. It would probably end our friendship and she means too much to me for me to do that to her.

I have been careful not to overstep, and cause her to push me away, but I couldn't take it anymore. I bought her a one way ticket to come and stay with me for a while. Her family doesn't know about what's been happening, so she doesn't feel like she can be honest with them about just how bad things are.

Now, what next? She's supposed to get on the plane in less than 3 hours, and I'm praying that she does. I'm kind of freaking out that she won't, or that he's hurt her again and she can't. What's the best way to handle her boyfriend? Is there any way to make him leave without involving the police? Is that even possible? I have no idea where to go from here.

Could you distill the essence of the text into 1-3 sentences?
<bot>: My best friend is finally trying to leave her boyfriend, and she's getting on a plane today to visit me for a while. Where do we go from here?
