In the world of 'stans and uber fans, accusations and threats from them get hurled around twitter and places like confetti, so it is no wonder that a lot of celebrities don't post (or post infrequently). The court of public opinion can be a nasty place.
I don't see how taking the breakup to a public forum is helpful for anyone especially for Aryn, who is clearly very hurt. Unless his behavior points to a pattern of abuse (ie, more than one woman telling their story), it seems it was a bad relationship left a lot of hurt and anger between them both. I hope she finds the happiness she wants and deserves.
And I wish the same for B and E. They've known each other for 7 years, so they must know each other very well enough by now so that it is not exactly spur of the moment.
