My question involves a roommate in the State of: Texas
My roommate has his ex-girlfriend at the house everyday without fail. She's always here unless she's at work, even at times that the offending roommate is not here. Though she has her own apartment not 5 minutes away, she never retires there. There are four of us on the lease (not her), and myself along with the others have talked with said roommate and his ex several times with no effect. She doesn't pay any part of the rent or utilities and I don't want her to, I just want them to be considerate of everyone else in the house and have her leave and act like a guest, rather than a tenant. I signed a lease to live with three other people and that's what I expect. This has been going on for about 45 days now, and I found out he did the same thing to his last roommate at another place for over 6 months.
I'm not concerned with our friendship anymore, what legal recourse do I have, if any?
