How can I get my BPD, NPD, DPD, BIPOLAR guy to leave my house

[Rose Quartz]

I started seeing someone 3 months ago and the last month has been HELL.  I've been begging and also his parents for him to leave my house.  I'm about to change my locks but afraid I will end up dead.  What's the best way to talk to him and get him to leave? I've done everything from being loving, horrible, and talking to his family.  He refuses to leave my house and has been here from day 1.  I did not think he would stay everyday but that's exactly what I got.  I am being harassed, and verbally abused every second of the day.  I need help.

Is concerning when you say you fear you'll end up dead if you change the locks.  Is there a past or current history of violence? Even if not directed on you,  but things like punching walls or throwing things? Do you have a support system (family,  friends) who are aware of what's going on?

Sometimes, when people are breaking then law, i.e, trespassing, you need to contact authorities.  I know it's not an easy decision to make.  Your safety comes first, and if you don't have control over your home, it doesn't appear that you are safe.
