While I was married to my exh and we had a roommate but then that wasnt good idea cuz my exh cheated on me with this roommate. So now we are divorced and this exroommate is my friend and we can get along just fine.
I wouldnt mind if she lives with me only under such agreement.
IF you are planning to have a roommate pls make an agreement on a paper and both of you and the roommate sign the paper.
