Definition of marriage abandonment??

[tdouce]

My wife had been found to be having an affair. I relocated for a period of 28 days and since my coming back into the house she has not spent a single night in the home. She stays at her boyfriend's(his parents) house until he leaves for work. She leaves at night and comes back in the early morning. Is she still considered as living in our house? What is the definition of marriage abandonment?
