MY AUNT IS GETTING MARRIED ! ( but for the wrong reasons !)

Hey Guys. My aunt is about to get married soon. The only reason she is marrying is because she is expecting with twins. She love him but not as much as he loves her. She gets anything she wants with a click of a button. But is it worth it. You know going through all the drama the dress, the hair, the shoes, the tux and on wedding night when its all over you are starting to realize you have made a mistake. Thats crazy. I just don’t want my aunt making this mistake PERIOD. SO WHAT SHOULD I DO . I mean as me being her bridesmaid, AND ME BEING HER NIECE, the wedding is gorgeous. But what really needs to look good is their RELATIONSHIP, RIGHT !!! I love my aunt, but she needs to be happy before jumping the gun like this !!! Only do that when you really love the guy.
WHAT DO YOU THINK ???
