Timeline this:
In the video she had Chelsea at her house before going away.
She went on holiday Monday. By the Wednesday she FaceTimes Chelsea who 4 days prior was a good enough friend to have at her house, and a good enough friend STILL by the Wednesday to FaceTime and ask a favour. In that phone call she decided she wasn’t phoning back because she wanted to pull away.
So in the 4 days of Chelsea being in her house, and the phone call, Steph has be debating not being her friend, but thought do it I’ll use and abuse her one last time before I hang up on her and end the friendship.
And Steph’s the one shouting the friendship isn’t genuine.
