I saw that, i did wonder , jacks girlfriend has also been tweeting about having been in a dark place and not getting out of bed lately , told everyone he was a twat
Not in anyway excusing whatever these two have been up to, but apparently the articles about Jack's gf have seriously twisted her words and taken them out of context (she makes videos about her life, in a recent one she talked about what she'd been eating and drinking that week, the headlines were about her "turning to alcohol and junk food" because of the Jack cheating rumours. She posted a vague mental health awareness quote on her Instagram about people in dark places, the headlines were about her being in a dark place).
She's very recently posted complaining about the media making things up and publishing lies.
I don't know wtf is going on in their relationship or if they're happy together or whatever, but if someone's saying tabloid articles about them are bullshit then in the absence of any significant evidence otherwise, I'll take their word for it.
