I'm not so sure. For a post that supposedly supports Tully there seems to be more than a few 'buts' there.
You know, it's a all a bit, 'I love Tully but I disapprove of this, this and oh don't forget this...' There's the implied disapproval over Tully cheating, which, if you're a friend 'offering support' should be irrelevant, especially on a public forum. Also, the comment about a friend "publicly embarrassing herself", which, again, regardless if it's true or not, is not the sort of thing a friend should come out with on a public forum, not if they're trying to support you.
I think a real friend would keep this sort of thing for a private discussion at an appropriate time, not this very public, half-hearted offering of love and support interspersed with barely disguised disapproval. A real friend would support unconditionally, at least in public.
For me, the quote about BB being a children's show is not what a friend would do. The implication that something very adult happened only stirs up more gossip and rumour. It may be true, but why the hell would a "supportive friend" stir that pot? How does that support Tully?
Sorry, I think the whole post is judgemental, self-indulgent nonsense. Regardless of what we viewers would think of Tully's behaviour; with friends like that, bloody hell.
