Could it be possible that the media made up the story that Jen tried to call Brad and AJ? I just don't see anyone doing something like this, especially a situation where the husband clearly left the wife for another woman.
I also do not think AJ is brilliant. She is beautiful, but she is not brilliant, IMO. Yes, she is doing some charity work. So did Princess Diana, who was also beautiful but far from brilliant.
I think that Vince Vaughn is a funny man and also kind of attractive. For some reason, I just don't see Jennifer and Vince as a true couple. She may grow to love him, but it just doesn't seem to fit to me. Of course, I know nothing as I just observe them occasionally on the news. I will say that I think that Vince is a Godsend for Jennifer. Vince seems very level-headed and down-to-earth. He also seems like a strong shoulder for Jenn to lean upon during this difficult time.
Jennifer has to be very wounded. Her husband left her, and her entire life story as well as his and his new partner's is being played out step by step. His new partner even had a baby. This has to be devastating to Jennifer. She is only human. In any case, I surely hope that she sees Brad for what he is. He is very selfish, IMO. He couldn't have cared much for Jennifer to have made this new life so swiftly.
Of course, we know nothing about the inner workings of the marriage. It must have been crumbling for a long time and Brad must have been extremely unhappy. That's why people look outside of their marriages and leave quickly when they find what they think is happiness.
Life is strange. It may hurt Jennifer now, but it will turn out as a blessing in disguise. She will find someone who truly loves her for her. As for Brad and AJ, I hope that they are happy, too.
