"It's hard to tell if I'm the backup plan or if the OM is the backup."
I think it's likely she doesn't know, either. But you have to remember not to push her in OM direction. I learned that from experience, believe me.
Those thing she's mentioned do sound positive, but be careful to take them with a grain of salt. If she's confused, she can change her tune quickly. But do pay attention to such things. The hard part is moving very slowly, taking it in and taking time to think about your responses and actions. I have had a very hard time with that, and often my impulses were not the best choices.
