Of choosing not to speak on her relationship with Pattinson, the “Spencer” actor reflected: " …

I was so self-conscious about seeming like an attention-seeker.

We were together for years, that was my first [love]."

Kristen Stewart’s journey after “Twilight” has been marked by her openness about her sexuality.

In 2015, she confirmed in an interview withElle U.K. that she was dating visual effects producer Alicia Cargile.

This marked the beginning of Stewart’s public acknowledgment of her relationships with women.

Stewart revealed that she had a disdain for her early experiences of hiding her relationships due to societal expectations. "
