DeAnna can't have it both ways. She either knew all along she was going to pick Jesse and she deliberately strung Jason/Jeremy along while they stated their great love for her. Feeding her ego and not caring about their feelings.

Or... she truly didn't make her choice till that last morning. In which case she was not ready to say YES to marriage to anyone. That would mean she was in love with the idea of getting married. She just picked Jesse as the one she thought was hotter when she had to make a decision.

Neither answer makes her a very smart person. She is either selfish and doesn't care who she hurts. Or she is so determined to get married that she just picks the one that she likes the best on the day of filming.

Neither answer should make Jesse's friends and family feel too good. He is either marrying a woman that is so self-centered she doesn't care who she hurts as long as she gets her way. (She does love to start sentences with "I" and end them with "me"). Or he is marrying a woman that didn't decide to pick him till the last minute. Oh that has to make him feel special. Being married is more important to her than who she happens to marry.

Jason and Jeremy dodged the bullet. Run Jesse Run...
