Roommate Troubles

[DeadKennedys]

Long story short, my roommate got kicked out of school, dragged back home by his parents, and owes alot of rent.

The greedy management that recently took over our apartment complex has filed a court case against us to get the money, but recently reopened it to include my former roommate (because the last landlord somehow didn't completely take her off the lease...). Which is pretty juvenile but money's what counts to them.

Because of this, he's said I won't be able to renew my lease in August. Now, I'm going down today to get this all taken care of, and I'm prepared to pay the debt in full ($1,800) out of my own pocket to get it dealt with swiftly, but since I'm going to handle this like an adult, somehow, I feel like since I have been paying my rent, I shouldn't be labeled guilty by association with a shitty roommate and should be allowed to renew in August.

Is there anything I can do to change his mind? Does anyone have any advice cause this has really been racking my brain. I joke around alot but this time, it's a really serious matter and I need all the advice I can get.
