Woah. How so? I don't see how they were or had been downplaying Jessica's importance to the group. I agree that moving on from someone who was a big part of their life is not simple, but what do we know? We don't know how they are feeling and coping with Jessica's leaving. We only see them trying to move on because it's smart and a business move since they are professionals.
And about not hearing any support from the girls, well, how can they when every single thing they say or do is scrutinized and thrown right back in their faces. Like, come on. Give them a chance, jeez.
Just like someone said above, don't look at it from a negative light. Try to be open-minded about this and think about both sides of the problem. I love both GG and Jessica and both just need to move forward.
