I had a similar scenario, but was consulted for an advise, a woman left the husbands house against his wish and spent 70days where she went to without calling the man all those while.
The man had already moved on after informing the both families what the wife did. The woman now came back and broke into the guys house when he travelled, on getting to know what happened he choose not to get back to the house for now,
So my fellow NLers do we termed her a burglar?

They were married. .... correct?
Was there any restraining order prohibiting the woman from entering the house?

They were not divorced yet correct? therefore she is entitled to have access/ gain entry to the home...

Though I don't understand what u OP meant by the Guy "moved on".....It was only 70days,...they haven't talked about the issue they were having..because according to U, he chose not to go to the house yet.... they haven't even separated....Therefore he's still stuck in that relationship...That is not my definition of moving on in my own opinion..
