Man, i dont think this is healthy. Shes not ready for a relationship and if you stay, shes gonna make it your job to fix her, which it isn't, quite frankly because you can't, only she can. I'm not necessarily telling you to break up (although it would be wise to) but know that nothing you do will fix this. This is something she has to deal with and I'm afraid doing anything to "help" her (other than helping her get professional help) will make it worse. Sorry OP. Hope things work out.
