The Season 8 finale of "The Big Bang Theory" ended with a major cliffhanger as Sheldon and Amy's slow-moving relationship came to a dramatic end just before it was revealed that Sheldon planned to propose to her.

After dating for years, Amy told Sheldon in the finale that she was fed up and frustrated with the lack of growth in their relationship and needed space.

"Being your girlfriend is so challenging, emotionally, physically," Amy told Sheldon via video chat. "This isn't easy to say because I love you, but I need some time to take a step back and reevaluate our situation. I hope you understand."

Devastated by the breakup, Sheldon began talking to the Gollum figurine on his desk and pulled out an engagement ring that he planned to give Amy.

Although fans were shocked by the awkward couple's breakup, series star Mayim Bialik hinted that their split may not be as finite as it appeared to be.

"I don't know if I consider it breaking up. The writers were very specific with the language that they used. Amy needed some time, she needed to step back," Bialik said during an interview with GoldDerby.

"The way I see it, this is a sense of breathing space and the relationship allows for that," she added.

The veteran actress also recently opened up about the way Sheldon Cooper is portrayed on the show, addressing rumors that he is autistic. When asked about Sheldon possibly having Asperger's during a panel discussion on Neil deGrasse Tyson's science show, "StarTalk," Bialik said all the characters would be on the "neuropschiatric spectrum."

"All of our characters are in theory on the neuropsychiatric spectrum," she said. "Sheldon often gets talked about in terms of Asperger's or OCD. He has a thing with germs, he has a thing with numbers, he's got a lot of that precision that we see in OCD. There's a lot of interesting features to all of our characters that make them technically unconventional socially."

She continued by praising the show for not changing or medicating the characters.

"I think what's interesting and kind of sweet and what should not be lost on people is we don't pathologise our characters. We don't talk about medicating them or even really changing them. And I think that's what's interesting for those of us who are unconventional people or who know and love people who are on any sort of spectrum, we often find ways to work around that. It doesn't always need to be solved and medicated and labelled," the actress said.

"And what we're trying to show with our show is that this is a group of people who likely were teased, mocked, told that they will never be appreciated or loved, and we have a group of people who have successful careers, active social lives (that involve things like Dungeons and Dragons and video games), but they also have relationships, and that's a fulfilling and satisfying life," she added.
