Of course she has feelings for you, feelings don't just go out the door overnight!

But her feelings aren't enough reason to stay. I had still had feelings for my ex when I left him, I still loved the bastard. But you don't go back to a man who beat you blue and purple because you still have feelings for him.
Well, atleast I don't. I didn't mean to sound judgemental

Feelings are fickle when they aren't backed up by anything tangible.

In your case, she still has feelings for you, but doesn't want to stop feeling up the other girl.

Evidence of her feelings being something worth paying attention to, would have been saying goodbye to the gf, without you even having to ask, suggest or even demand.

Something she outright refuses to do.

More examples of feelings being irrelevant in the bigger scheme of things would be:

* "I feel like running naked down the street".

* "I feel like hi-fiving my neighbour in the face with a chair!"

~ Just because I feel like it, doesn't mean a damn thing.

Children are ruled by feelings because its still their primary source of information, they don't instinctively know to cross reference it with repercussions, conditions, or even reality etc.

* My daughter will feel like staying up later than usual not realizing it makes her cranky.

* My daughter will feel like having cupcakes for supper because they're pink.

* My daughter will feel sad and start crying in the shop because I said no.

So, my 2cents?

If you're seriously going to consider keeping this woman around, try thinking on a much larger scale than feelings.

Example:

* Do you really want to stay with someone that lies to your face with ease, brings her lover into YOUR home and then refuses to say goodbye to her?

If your answer is yes, PLEASE ask yourself why you're willing to stay with someone who's deceitful, disrespectful and displays zero sense of loyalty toward you...

*How will she be able to regain your trust when she won't even cut ties with her lover?

Do you expect it to magically appear with time?

* How will you feel and react the next time she makes a new friend?

Will you start spying on her again for peace of mind?

* Why are you SO willing to settle for someone who isn't even at all sure she wants you?

Don't you know you deserve better?

*How do you expect to salvage your relationship when she's unwilling to even try to make an effort?

*What is sooo valuable about this specific relationship that you absolutely have to make it work, what are you getting from her that you cannot get elsewhere?

Because the way I see it 2 timing cheaters are a dime a dozen, you can get plenty of that before you even cross the street.

Sorry my post was so long, but I cannot sit back and say nothing when you are ready to make a HUGE, possibly/probably damaging decision based on something as fickle as an untrustworthy woman's feelings.
