"One of her issues is that she has feelings for her previous romance and hasn't been able to move forward. He has recently been texting and e-mailing her once again."

I think this may be the key to your problem right here - she still has feelings for her previous romance. She doesn't want you to contact her at the moment - one reason may be that she's rekindling this romance, but she may also be feeling confused about her feelings for him and her feelings for you. She may actually need the time to sort out what she thinks and feels so that she can continue the relationship she feels is best for her.

You could email or text her and ask her directly if this is the case. It may be the impetous she needs to move on.
