I moved in with 2 of my friends about 5 months ago. We had a lease for 6 months in total, from May 1st to Oct 31st. Well, my one roommate up and left, leaving my other roommate and I to pay the full 800 between the two of us. Now, the problem is, the reason all three of us moved together was so we could afford the rent. When all three of us were living there, we paid 266 each on the rent, then when he left, we had to pay 400 each. Which may not seem much, but we did not make much money with our jobs. So, I have since moved back into my mothers house, as did my other roommate. We have one month left on the lease, and the landlady is coming after me for the full months rent. She is not getting a hold of either of the guys, but just me. So I am the one dealing with the stress. So, my question is, what to do? I know I have to pay the last months rent due to the legal lease. But should she not have gone after the guy who ditched first to make him continue paying for his share of the rent? He is on the lease as well, not just me. All three of us are. I have given her his contact information, but she is only bugging me. What should I do?
