Good question....
I have a friend who dated and fell in love with this guy in high school. Well they got married....had 3 kids.....got a house. Everything seemed picture perfect for 7 yrs.....even up to a few months ago. Well she RSVP's to my other friends wedding and tell her that shes gonna be bringing her bf and NOT her husband. I was shocked to hear this. Her and her husband are in the process of a divorce. She seems to be perfectly fine with this. SHe doesn't seem one bit upset. I think IM more upset then anyone else!! Really sad........ She says she hasn't been happy for awhile and she met someone else and now shes dating him......and she wants out of her marriage.
I guess sometimes people just fall out of love.......or just change....or give up.....or find something that makes them happier......who knows.... All I know is she was the last person I expected to get divorced. They seemed so happy even up until like 4 months ago.
