Should She? Shouldn't She?

Allie while engaged sees a picture of Noah in the newspaper and decides to go see him. She tells Lon and her family she just needs to get away from planning the wedding because it was really stressful. Lon being the understanding husband lets her go with no questions. She almost turns back many times but something kept her going. She went and saw Noah and they had dinner and he asked her to come back. Immediately they reunited and were back in each others life. There was just one complicated detail, Lon. I don't know what i would do if i was Allie in this situation. She is caught in between two lives. One with Noah and one with Lon. These two paths would make completely different life for her and she has a really hard time choosing.
