Dr. PH,
Please explain something to me. How is it that a couple can date for a long time, say five to 10 years and not get married but after they separate, one person gets married after 6 months or so of dating someone else?
I don't think people should take it so personally. Feelings might be hurt, and understandably so. However, people change. Five to ten years is a long time. Take for example, my high school friends. Two of them dated their boyfriends since we were in high school. After numerous years, one if them got married. The other one and her boyfriend just broke up not too long ago. If you think about who you were when you were in high school, even college to now, are you the same person with the same goals/wants in life? Most likely not. Perhaps the person who remarried quickly happened to meet another person who was better suited for him/her.
Or if you want to go the negative route, you can think what everyone else said.
Just remember, people change!
