I just got engaged a week ago. Yea!!! I'm already feeling the stress of my parents divroce, which happened when I was five. My 16 yr old sis is making comments about not being wanted at dress shopping. This comment is directed at my mom, who is not a good mingler with anyone, and is the same way when she's put in a room with my stepmom & sister. My mom is already giving me, "if I were you..." about who I should have in my wedding party. How do I handle all this? How do I make everyone come together for this occasion that I'm over the moon about and want EVERYONE to be a part of?
