Matter in what way?
Doesn't matter to me, an ex girlfriend can be pretty far from connected , pretty poorly matched, there may be a good reason that they did not stay together. I don't think an ex can be a positive reference, presumably she has found better since.
I read that article, I was struck by how little Paul Ryan was actually discussed, went immediately to other people who had interracial relationships. Really what can I learn from an article like that about Paul Ryan?
For all I know after reading that I have no idea at all about Paul Ryan I didn't already have.
