Roommate From Hell Retaliating

Roommate 22 F, Me 23F, fiance 25

My roommate decided to move out after I told her I no longer wanted to be apart of her custody court case. That's fine with me, then she offered me money to continue participating, and I said no, she confirmed she was moving out. She was living somewhere else for a month or 2 atp because her sister (not on lease) was living here rent free, was more than likely doing drugs in the bathroom to the point of passing out and we had a disagreement on that, so she moved and continued to pay rent to show the court.

I did not force her to move, I didnt ask her to, I didnt give her a deadline.

• Anyways, now we're here. Over text she threatened to blackmail me to our leasing office and cited us dropping out of her case as a direct reason.
• mentioned sending screenshots of me asking when she's coming by to get her stuff to her custody lawyer who said he was... confused? well yeah he's a custody lawyer and she already confirmed she's moving on her own free will (AND told the court that she was moving on her own free will) and asking when she's going to get her stuff isnt illegal, and asking her if she's planning on signing the addendum after she MOVED isnt illegal. This is clearly intimidation.
• she stole a HUGE coin jar with bills worth $80 maybe. none of my neighbors had cameras so I dont have proof other than a 2 ft tall jar filled with coins vanishing the day she collected her things. Even if I dont have proof (besides it disappearing from the SAME spot it's always been??), should I report this anyways to support my retraining order against her?
• She did end up contacting our leasing office to try to have us evicted, and the leasing office concluded today that the claims weren't true and we wouldn't be evicted and would move forward with the addendum. She said I smoked weed, had extra cats, so on. anything to try to get me evicted.
• She contacted my fiance's job to try to get them fired. She said they were a drug abuser that also abused animals (they work with animals) and should be fired asap for everyone's safety. Luckily their job knew about her retaliating threats already with our lease and nothing was done about the call. She probably called around my town to see where I worked because she doesnt know im self employed. This was probably another way for her to make sure we got evicted.

TL;DR I have documentation of her contacting the leasing office to get me evicted, documentation of her contacting fiance's job to have them fired, and documentation of her telling us she's going to blackmail us falsely for not being apart of her case anymore.

question: is this enough documentation to move forward with a restraining order against her before or after she removes herself from my lease? what other steps should I take?

Besides the restraining order, is there something I can do with my leasing office? After inspecting our house with an OFFICER present, I let them know about her stealing my money from my house and they couldnt give less of a fuck.

They sent an email offering us 2 options, she agrees to be removed or either of us can take legal action against each other to forcibly remove them. She doesn't have the money to afford the leasing office's attorney but it's entirely possible she'd put herself into debt to make sure we're homeless (after we saved her from being homeless on the street).

I dont think they called her to let her know the addendum was ready to be signed by her either even when I let them know she wouldn't be checking her email. They couldn't care less about by safety at the moment.

I asked about changing the locks and they shrugged and glossed over it to get to explaining the options we had (addendum or legal). She has none of her stuff here and refuses to return the key which is her legal right, but she's stalking us, she's stealing from our HOUSE with the key, harassing us. I feel like im on firewatch in my own home 24/7 to make sure she doesnt steal more from me. I have a camera that records on a cooldown, im seriously considering paying for a 24/7 ring camera or something.

please help me! I've never rented before or been harassed at this scale.
