According to multiple reports, the couple broke up earlier this month.
The source said Malik and Hadid "have insane work schedules that would put pressure on any relationship".
Gigi added on her own Twitter, "Breakup statements often seem impersonal because there is really no way to put into words what two people experience together over a few years.not only in the relationship but in life in general I'm forever grateful for the love, time, ad life lessons that Z and I shared".More news: Arturo Vidal: 'Bayern Munich not scared of anyone in Champions League'
The source continued: 'This is definitely the end for now, but this isn't a bitter split and they both have respect for each other.
'This is their journey and I'm just here to support both of them as long as they make each other happy, working through things then I'm happy'.
The pair started dating in November 2015 after meeting a Victoria's Secret Fashion Show afterparty. The source explained, "It's a mutual decision so no one has completely ruled out a reunion in the future, but for now that's not where their heads are at".
