Girlfriend Wants TRIAL Move In – Leo and Rebecca Buzz Question

Leo and Rebecca Buzz Question - Been wanting to move in with my girl for over a year and she's all for it now. But she threw out 'IT'S A TRIAL MOVE IN'! Like how is that suppose to make me feel. I've got my own apartment and stuff and I'm ready to go half's with her on everything at her place but she throws out 'Trial'. What do you think?
