Mike and Heidi were an interesting couple, you could feel the chemistry between them so why did it go so wrong?
To some degree, I believe the ixperts got it very wrong with these two. From what I could see Mike was the one who needed guidance, yet they focused upon Heidi, blaming her for being unreasonably upset at some of Mike's actions. I really wanted Mike to be helped to see where he was going wrong, he needed that help.
The final date was a disaster. He planned something entirely to suit him, without a single thought for Heidi. Something like Mark and Ning's tree house, or Cam and Jules date would have suited Heidi, so simple but lovely.
Moving onto Cyrell and Martha. We enjoyed Martha's "apology" so much, we had to watch it twice. I love Cyrell, she's a legend.
I believe Martha and Michael will not last. At some point Michael will wake up and realise he's being completely dominated by Martha. I hope so anyway, because he seems like a decent person unlike Martha.
