Brian, I can only offer my experience in this.

When I met my W, she was in an abusive R. Myself and a few friends became involved in an intervention that had her BF removed from the house by police escort. As much as I didn't "see" it coming, I became attracted to her and she, to me... and the co-dependent M that I am now at the end of is the result.

Be there for her, just be careful that both (or either) aren't seeing you as the knight in shining armour. You are a good man and will make a great BF or H in the future, even now... just be careful and take things slow... that the two of you are "ready" and it's for the "right" reasons...
