Someone who is more knowledgable about it may want to chime in and contradict me, but my wife at one point also wanted me to move out. I was advised by a family friend that under no circumstances should I do so because, if I did, it might cause some issues for me custody-wise, particularly if the split ended up getting ugly.
Particularly because my wife already had another place she could go (her parents), I ultimately told her that while I 100% understood her feelings, I had no intentions of moving out but that she was obviously free to go whenever she felt ready. She hasn't left yet, so...
