I have recently signed a new lease and moved into my new place. The place I have moved in is a unit in an apartment complex. The manager of the complex told me I cannot have guests for more than 14 days per month in a consecutive manner and cannot live with people whose names are not on the lease. The manager emphasized that since my girlfriend's name is not on the lease (and I cannot add her to the lease for some reasons) she cannot live with me here but it is okay if she wants to sleep over.
The thing is my girlfriend is currently staying with her parents but we have been planning to move in together for a while. However, what the manager told us has become a very bothering thing for us since she is not legally living with me as she has not officially changed her address but she will be sleeping at my place, pretty much almost every night. We cook dinner together when we are home around 6-7pm (which happens often) and then sleep until tomorrow morning around 7am when we wake up and go to work. Although she will stay at her parents' place every couple of days (for a day or two) she has brought her clothes and personal items such as tooth brush etc to my place.
So my question is would my girlfriend coming home around 6-7pm every day, cook dinner and sleep over at my place be considered as something illegal? Is she actually living with me? What is the legal definition of "living"?
