Also, don't acknowledge her when you first come in. I know its hard but just ignore her for awhile. No giddy, goggly talk by the gf or anything either. Just let her calm down.
I am not an expert at all but just something I thought off while reading this. I am not sure it will work or is the right way to go about breaking the pee habit.What if you greeted and played with her outside when you first get home. That way she gets a lot of the excitedness out of her system before you let her in the house?
This is an easy problem. Pups shouldn't be left alone with other dogs when you're potty training. You said she can be outside for hours in another post and come in and potty. She's out with the other dogs distracted. I think you need to crate her, no free time with other dogs. Let her out of the crate to potty. If she doesn't go, back in the crate. There is no benefit to letting a pup have a bunch of free time unsupervised with other dogs. All that can really happen is pup will get hurt playing rough.
