Lidl recently changed her profile pic to her as Hitler putting Null into an oven. My fanfiction is that they had a bad breakup and we are seeing this play out in real time:
Lidl: ‘Come visit me in Belgium I’m so horny.’
Null: ‘Sorry I’m too poor’
Lidl: ‘God you’re such a faggot’ *changes avatar*
Null: ‘Fuck off bitch’ *bans Lidl*
Null moving back to America made the time difference hard for them to maintain good comms. Time difference can be a huge stress on a relationship. One or the other was tired of waiting and wanted to move on.
