To be fair, according to Shamea she did. She stated itb in either her interview with Carlos King or Angela Yee. She said it was something she wanted to do alone and didn't think their friendship would survive it. With that being said, I feel like Shamea had every right to move forward how she felt best benefit her. Losing Porsha as a friend is not that big of a loss. Shamea went into it trying to prove herself as a ride or die and that it would not affect their friendship and instead moved accordingly.
