I've said it before and I'll say it again,.....she's confused. She's ambivalent. She wants a divorce. She wants a happy marriage. She loves you. She hates you. That's life. Those are emotions. She is being swept over by emotions. As long as she is confused and has feelings in both directions, that is good. It's when she only has negative feelings or no feelings at all that things are really bad.
Have your friends over. Don't mess with her stuff. Respect. Everyone wants respect. She's trusting you by leaving her stuff there. If she can tell that people went through it, then she will move all her stuff out. If you want her to trust you, you have to be trust-worthy. In everything that you do.
