“That was a genuine option for me, quite a few times in my life. Then I don’t have to be this bad person because I don’t have to be here any more.
“And I thought about that and I thought, ‘Oh my God I haven’t thought about that in six years’.”
While Amanda’s relationship continues to grow with her husband-to-be, Martin is now in a relationship with fellow actress Rachel Mariam, 29.
