I think guys do that all the time. Women too. We all wondered why Travis wouldnt take that risk with Moana. And she has said recently that they still talk "all the time". But yet, even though both were single (dont know if they are now) after the pressure cooker of the show was over, he still didnt choose to try later with Moana. Travis was so very taken with her. But in his judgment, they would not make it as a couple. So he chose not to try.I do believe that Andy will think about Bevin and wonder what if he had taken the risk
I think that Andy knows what he needs and wants. He was very good at judging personalities and dumping the women who were not compatible with him. Excellent in fact. Many , if not most, men have felt real electricity with a woman they choose not to marry. That doesnt denigrate their love or their marriages.
Refraining from taking a risk is a negative thing only if it prevents you from finding what you want in life and going after it.
