My question involves a roommate in the State of: Texas

My roommate has signed another lease, and we have only fulfilled 5 of the 13 months of our lease, we both signed the lease. she says she is going to pay both of the apartments leases but i don't think that she will be able to come up with the money. and i dont have any friends that need places to live at this time.

If she moves out and doesnt pay will i have to pay? will that be on my credit? can i do anything so it wont be on my credit? can i get any of that money from her threw court?

Thank you in advance for any answers.
