Alex and Amanda broke up, but were never married:

My prediction for the final 2 is Gwen and maybe Helene.
I think he will cut Brooke based on the fact that (as AlphaSigLana pointed out so accurately) he comes from money and her father is incarcerated....I think that will play a big factor. I don't really see a lot of spark between he and Angela. Maybe that will change.
Frankly, Helene is the "Shannon" from Bachelor I...confrontational and in his face.
