Story of my life...being the "friend" alongside a woman in/out/near a relationship can cause confusion, usually at the expense of the female involved.
The true, morally correct answer: tell her you need to step back from her, especially with you spending time like
that. She'll probably be pissed, but as long as she understands you're looking out for her best interest, she'll eventually get over it, and probably respect you more.
The also true, but morally wrong anser: take the ride as it comes.

She's not your girl, and you're not her man. Her issues are not yours, so take best advantage of the situation as you can...
BTW, the last part didn't come from me.
Yeah, not from me...
