While Chris didn't confirm the woman is his girlfriend in his Instagram post, he captioned the post with a very heartfelt and romantic quote by American novelist F. Scott Fitzgerald.
"She was beautiful, for the way she thought. She was beautiful, for the sparkle in her eyes when she talked about something she loved," Chris wrote.
"She was beautiful, for her ability to make other people smile, even if she was sad. No, she wasn't beautiful for something as temporary as her looks. she was beautiful, deep down to her soul - F. Scott Fitzgerald."
Chris' photos included the pair smiling for a selfie at a festival, drinking fancy cocktails at a bar, cozying up to one another in a car, and a solo shot of Caitlin hugging her dog.
Chris also recently uploaded images on his Instagram Stories of Caitlin and himself partying in Las Vegas.
Chris is definitely off the market, as he changed his Instagram bio to read, "Now Taken."
The Boston-based real estate agent also confirmed he has a girlfriend and is exclusively dating someone in a late May Instagram comment.
Comedian Michelle Collins started a "find Chris love campaign" on May 20 via Married at First Sight's official Instagram account, which posted a video of Michelle gushing about how Chris deserves to find love because he is "adorable... employed" and actually "looking for a long-term relationship."
Chris replied in the comments, "Thanks [Michelle] for the love and support! You'll be happy to know that I'm not actually single anymore, and I'm very happy."
"Thanks everyone for the kind words," Chris continued. "I look forward to watching the last two episodes with everyone."

Viewers last saw Chris flying Married at First Sight alum Olivia Cornu from New Orleans to Boston for a date, and he also invited her on a Season 14 cast getaway to Cape Cod. Chris and Olivia's time together aired during the Married at First Sight: Where Are They Now? special in early June.
The Married at First Sight: Where are They Now? special for Season 14 likely filmed in February or March, about five months after Decision Day, but there is no sign of Chris and Olivia still being together.
Olivia hasn't mentioned Chris on her Instagram account, and Chris also hasn't posted anything about Olivia on social media.
Prior to asking Olivia out, Chris had been married to Alyssa Ellman, his Married at First Sightmatch. However, the spouses were only together for 12 days before Chris decided he wanted a divorce.
After Alyssa and Chris tied the knot as total strangers, Chris' groomsmen essentially told Alyssa how Chris can be condescending, argumentative and a bit arrogant when expressing his opinions.
Alyssa also admitted that Chris seemed immature and he wasn't her type at all, and so she determined in only a couple days time that they weren't a good match.
"I don't see how we're compatible. We have no shared hobbies, in my opinion, and we don't share the same core values and beliefs," Alyssa said. "And that's where I feel like things got misconstrued and messed up."
Chris claimed on an episode of Married at First Sight: Afterparty that Alyssa had called a lawyer trying to get out of her marriage before traveling to their honeymoon in Puerto Rico and she wouldn't give Chris her phone number so they could stay in touch.
Chris also alleged that Alyssa had refused to sit next to him on the flight to San Juan and didn't try to get to know him on a serious or deep level at any point.
During the pair's honeymoon, Alyssa even expressed "hate" and told a producer that she couldn't tolerate Chris' personality and hand gestures. She spent most of her honeymoon trying to avoid one-on-one time with Chris.
During a therapy session with Married at First Sight expert Pastor Calvin Roberson one week into the process, Alyssa announced how she'd like to continue on with the show, seemingly so she could keep hanging out with her fellow Season 14 brides and enjoy the ride.
But when Alyssa suggested to Chris that she'd like to move forward on Married at First Sight without living together in the Boston apartment the show had provided for them, Chris determined his "Decision Day" had come early, 12 days into the process, and he wanted a divorce instead.
"I think there are a lot of reasons to still be here, but I don't think marriage is the one that you're here for," Chris told Alyssa during their breakup conversation.
During the show's reunion special, Chris admitted he would've been done with his marriage much sooner had he heard the terrible things Alyssa said about him when she thought she was just venting to producers behind the scenes.
"[In particular how she said] that I'm a f-cking used carsalesman who sells houses," Chris complained.
"I didn't realize the extent to which she had said bad things, had said insulting things, had said disgusting things. When you say stuff like that about somebody, you're just not worth my time at that point. No one deserves that."
Alyssa apologized to Chris and insisted she had "the purest intentions" going into the show and during the process. Alyssa admitted that she had meltdowns because she was so upset the process hadn't worked for her.
On the Married at First Sight: Where Are They Now?special, Chris and Alyssa were cordial and able to hang out with their fellow cast members in a pleasant setting.
Alyssa was shown going on a bowling date with MAFS alum Ryan Ignasiak. Alyssa, however, dumped Ryan after their first date because she found out he was friends with her "enemy," co-star Lindsey Georgoulis, and had never told her.
In addition to Alyssa and Chris' marriage, two other MAFS14 couples broke up by the reunion special: Lindsey and Mark as well as Jasmina Outar and Michael Morency.
Steve Moy and Noi Phommasak, however, stayed married at the end of the extreme experiment, as did Olajuwon Dickerson and Katina Goode.
Married at First Sight's upcoming fifteenth season is scheduled to premiere Wednesday, July 6 at 8PM ET/PT on Lifetime.
