you could ask her - but that might back fire.....although she knows you know about the EA.
You could also listen to her cues - what did they do or talk about?
Since you already know about the A, I don't think it would hurt to ask her what she saw in him, or what he gave her that you weren't @ the time. Matter of fact, scratch the first part - don't make it seem negative.....like what did you see in that POS but what did he do for her - that you weren't at the time - meaning you can and WILL do this for her now if it's anywhere at all in your scope of ability.
