'Every person's priority should be to empower their partner and support them to express themselves and be confident in their body!' he wrote.
Michael also responded to other fan questions about whether he's still dating Martha.
'I'll get this one out of the way early,' he wrote. 'We are definitely still dating and any article suggesting otherwise is complete bulls**t. We've been together seven months.'
Another fan asked: 'Are you still living in Sydney with Martha?'
'She's been living in Melbourne for the past four months! But she'll move back to Sydney shortly and we'll do long distance until the time is right for me to move,' he wrote.
The news comes days after the reality star couple were spotted arguing in public - just one day after the MAFS finale aired - at a café in Chatswood, Sydney.
In pictures obtained by the Daily Mail, the couple, dressed in activewear appear at breaking point, with Martha seemingly sobbing into her hands at one point.
Michael looked glum and tense while distracting himself with his phone.
They were having a really tense conversation and then she just started crying as she was waiting for her food,' a source told the Mail.
'They both looked really uncomfortable and stressed. The chemistry you see on TV just wasn't there.'
Another source added: 'Martha is in a really bad place mentally, and has struggled with all the criticism from her actions on the show.'
