Tayshia recently revealed on The Ellen DeGeneres Show that Zac is the most "husband material" out of her group of men, which led Ellen DeGeneres to believe Tayshia picked Zac at the end of her journey to find love.
And when Zac shared that he was falling in love with Tayshia, Tayshia actually said the same words back, that she was also "falling in love" with him.
Zac told his mother Beatrice during his "hometown" date at The Bachelorette resort he wanted to be a husband and a father and welcome children in the near future, although he previously told "a lie" in saying he'd just be happy as a single uncle.
Tayshia apparently made Zac want these things out of life, and Tayshia gushed about how everything felt "easy and natural" with Zac and she had "zero hesitations" about their relationship and whether he'd make a great life partner.
Will Zac and Tayshia end up together and live happily ever after?
Until viewers can watch what happens next, let's learn some things to know about The Bachelorette suitor, who seems to be a frontrunner on the show at this point.
Below are twelve facts Reality TV World has compiled about Zac Clark.
Zac is a recovering alcoholic and former drug addict who also abused both illegal and prescription drugs.
In a 2014 speech, Zac reportedly said his addiction resulted in "15 years of lying" and culminated with a four-and-a-half month stint at a addiction recovery facility that helped him turn his life around.
According to a report the Reading Eagle published at the time, Zac spoke at a gathering at Alvernia University in January 2014 and detailed the lengths of his addiction.
Zac apparently once complained of a pain in his side and asked doctors to remove his gall bladder so he could have access to heavy painkillers. He was also thrilled to receive drugs after a brain tumor was removed from his head.
The report says Zac snorted and smoked OxyContin, shot heroin intravenously, smoked crack and did "whippets," which is inhaling bursts of nitrous oxide for a short-lived high.
Zac was eventually arrested for possession of crack and driving while intoxicated, and then he decided to turn his life around and never look back.
Zac tries to inspire others not to repeat his mistakes
In 2017, Zac co-founded a recovery program with a variety of services called Release Recovery with his friend Justin Gurland to help people reclaim their lives after struggling with addiction.
Both Zac and Justin had their own personal journeys in recovery, which made them want to share what they've learned with others on the same path to sobriety.
Zac was previously married
During his speech at Alvernia University, Zac reportedly revealed he got married in his 20's after graduating college.
According to Zac, his addiction even dominated his wedding planning, as The Bachelorette bachelor admitted his biggest concern was trying to figure out how he would be able to get drugs during his honeymoon in St. Thomas.
"I have got to leave the country for 10 days and for a guy with a serious, serious drug problem, that's not cool," he told attendees, according to the Reading Eagle.
Zac is a former athlete who initially planned to pursue a career in sports
Zac, standing 6'1" tall, played three sports in high school and later played baseball in college, but his focus was unfortunately on partying at the time.
Zac says he loves Philadelphia sports and dreams of sharing a Philly Cheesesteak with his future wife while watching the Eagles win a Super Bowl.
Zac has run numerous marathons for good causes
Zac runs the New York City Marathon every year -- six years straight as of 2019 -- in honor of a friend's brother, who died from his own battle with addiction.
"To me, the NYC Marathon embodies something that our nation needs more of: LOVE. It is the one day of the year that the entire city comes together and cheers for the same team. It's about shared passion, inspiration, and teamwork," Zac wrote in a November 2018 post on Instagram.
"It has become my favorite day of the year because of this spirit. As we continue to face a challenging social climate, I encourage EVERYONE to continue to take action, get behind causes that matter to them and keep spreading the LOVE."
Zac says his sister Kat is one of his "rocks." He calls her "a badass" and a "hero," and he apparently adores his niece and nephew.
Kat actually nominated Zac for The Bachelorette, so Tayshia can thank Kat for Zac's participation on the show this season.
Zac once "cheated" on a girl, which initially made Tayshia's head spin
Zac revealed during a lie-detector test on a group date that he had once cheated on a girl, which really worried Tayshia because she has said infidelity and unfaithfulness are dealbreakers for her in relationships.
However, Zac only "cheated" on his girlfriend in sixth grade.
While dating his young girlfriend, Zac met someone else and kissed the new girl at a bowling alley.
Zac had "one of the most powerful experiences" of his life on December 14
Zac took to Instagram on December 14 and revealed he had reunited with his "angel" named Rhonda Jackson, who was shown smiling with Zac and holding a massive bouquet of flowers in the photo.
Zac shared with his followers, "On August 28, 2011, I walked into the @pncbank bank in Camden, New Jersey and I met my Angel, Rhonda Jackson. Rhonda didn't know me, didn't care what I looked like and didn't judge me. She just knew that I needed help as I tried to cash a forged check so I could get some quick money and keep getting high."
Rather than calling the police, Rhonda apparently called Zac's father, whose name was on the check as the checking-account owner.
"[Three] days prior, I had stolen a handful of checks from my father's desk and left without a word to anyone. For days, my family looked for me but no luck. Rhonda's call not only told my father that I was still alive but where I could be found. He rushed down to the bank just in time before I disappeared back to the streets. Two days later I was in treatment getting help and the rest is history."
Zac apparently tracked Rhonda down to thank her for going the extra mile to help him.
"I was reunited with my Angel. It was one of the most powerful experiences I have ever had. She still works at the same bank! I met my hero, I met the woman who saved my life. I got to talk to Rhonda about her children, her faith and her passion for making beautiful prom dresses," Zac continued in his Instagram post.
"She remembered the day vividly and we hugged like we had known each other forever. In a world that is filled seemingly with so much apathy, Rhonda Jackson taught me a valuable life lesson. Always treat people with love, always believe and always do the right thing."
Zac concluded, "You never know whose life you might be saving. Thank you, Rhonda for saving my life. There are no coincidences."
