Carrie, you're not a failure! Potty training can take a loooong time. It's not your fault. Here are a couple of thoughts for you.

I personally love what the others call "poochie bells". I just use a couple of jingle bells suspended from the door knob of the door that the dog uses to go outside. However, you need to know the downside and that is that they'll frequently ring the bell just because they want to go outside and play. Could be a problem for you in an apartment.

If she already understands "outside" and goes to the door, watch her like a hawk. I think it's possible that she will soon (if she hasn't already) start going to the door to let you know that she needs out. I've had dogs who would come "tell" me that wanted out, but I've had others who would just go to the door.

As far as the hiding to potty inside, be sure that you are NOT reprimanding her for going inside. She learns that it's dangerous to potty around you. Therefore, she wants to hide from you when she goes. If you catch her in the act, say no and rush her outside to finish. If you find a "mistake" after it happens, say nothing, but vow to watch her more closely!
