@joseph99,
If it were me in this situation, I'd back off being in touch with her until this all settles out and she makes up her mind. You really need to focus on your own happyness too, you know. It's all well and good to want her happyness, but right now at this point...you might be taken advantage of...even unintentionally by her.
Until she makes a definitive decision, your seeing her only fogs her mind while she continues with indecisiveness.
Be strong in your resolve 'cause until she works out whether or not she wants let go of her ex and her relationship, you're her convenient distraction. Sorry if that sounds harsh. Been there myself. You can't convince her either way as she has to convince herself of where her heart and future relationship lies.
It'll take a lot of self-confidence on your part to stand back and remove yourself. Reality might be that she may not be ready to commit to anyone - hence her cause for putting herself in this romantic triangle in the first place.
