Again....this isn't out of the ordinary, when you get cheated on you feel unwanted and unattractive, but if she wants to do that it's purely her choice and I'm certainly not going to judge it.
This is her twitter, and she's a young 20something, I don't see why she needs to take on the 'moral high ground' when she's been treated the way she has by Tully.
In an ideal world she would, but she's young and probably quite inexperienced with heartbreak.
You speak of giving Tully leeway with her mistakes and choices but you don't do the same with Tahlia?
