I don't suggest she move out unless she really wants to. It seems like you are pushing her out. I admire your fearlessness. It will serve you well. Since she's ended the R with OM, give her time to grieve it. It's a real loss.
While she's in a tizzy about her life, you be the rock she really needs.
It's OK for her to tell you how miserable she is. Listen, validate, don't judge. She is miserable because: 1. She doesn't know who she is, 2. She's probably a little depressed, 3. She's addicted to this online game, 4. She just "lost" someone she thinks she loves, 5. She's comparing a fantasy online relationship to reality.
Give her time to sort our her feelings. You be the one to go on a personal journey of transformation. You already seem quite centered and strong. You happiness and clarity will stand in a contradistinction to her misery. She'll eventually realize she's better off with you.
But...she's got a lot of grpwing up to do. She's got to change.
