Mostly though I'm wondering if their claims will hold up in court.
There is absolutely no way that anybody could accurately predict what would happen if they actually took you to court. That said, if they pursue you in small claims court which is inexpensive and informal, you will get to tell your side of the story. If they prevail, then they have to figure out how to collect any judgement against you.
I recently was asked to move out
Asked or demanded? Big difference. IN your subject line you mention eviction, but it sounds like you left voluntarily. Big difference.
I spoke with a tenant's hotline and they told me legally I didn't have to move out.
Maybe you should have listened to that advice.
was told I was not able to leave my bedroom.
Are you like eight years old? Come on!
Now they are saying they will sue me
Saying and actually sueing are two different things. Until they actually sue you, ignore them.
My old roommate has been sending me threatening text messages and came to my work yesterday to "serve" me with a handwritten letter warning me to return the key and pay the bills or else they will sue.
Report the threats to law enforcement if you believe that they are serious. If your ex-roommate shows up at work again, ask your boss to call the police and have her removed. Return the key and forget the mini-fridge.
