I have a friend living in WI. He moved out of his rented home leaving his son and wife to stay. A couple of months later, he went there (don't remember why) and when he went to the door, he could see her and her BF making out on the couch. He broke a window to get in. (he felt justified -- he was still paying the rent and his child was asleep in another room). He did a lot of screaming and yelling at her, told BF to leave.
She called the cops. They arrested him for breaking and entering and charged him with domestic violence.
He was told by his judge that once you move out and establish another residence, you have no right to the original residence, whether or not you are paying the rent.
Focus on what is legally relevant, not morally indignant or petty.
