A roommate and I signed a lease the first week of February. Up until recently everything was fine. There was one of his friends staying with us for free. After months of requesting the friend leave and nothing happening I finally kicked the friend out myself. Shortly after (2 days later) I return home from work and the roommate moved out. There was no warning or notice stating he wanted out. We both signed the lease and rent is due shortly. I have called and text the roommate multiple times and have no response. He still has his key and left me with all the bills and rent to myself. If we are both on the lease is there something that can be done? I don't want to be the only one held accountable for the up coming month.
