"The more I am talking about it, the more I am realising it's not going to work," a heartbroken Mike said before admitting he's unsure whether the couple has the strength to survive outside of the experiment. "It is just tough to accept that. It's a breakup, for real."
Holding back tears he continued, "I really don't think I can do it. I hate saying goodbye. This is why I am single at 44. I let her in and here we are, again. I don't want to say goodbye."
Heidi also returned home to her family and friends, who, unlike Mike's clan, wasn't convinced her husband was the right man for her.
"I really like Mike. I am still not 100 per cent sure. There are things that have happened that we've become aware of," her friend said, refusing to sugarcoat her opinion. "There have been a few red flags and they are concerning," her other pal added.
