Agree. It's the only voice she has in this situation. Tully is on BB and in the public eye and blah blah and people are making reference to Tahlia all the time so she probably wants to be able to vent in a similar forum
I'm not advocating in, in fact I would recommend she (or any one else) never use social media for something like this. But I can understand how at the age of 22, after being betrayed on TV, and then having it rubbed in your face some more, you would feel the need to vent your own thoughts.
Tully is being so smug as if she was the one wronged by Tahlia. If Tully didn't want someone breaking up with her she shouldn't have cheated. It's relationship 101
