Jennifer Aniston thinks her relationship with her boyfriend, Jim Curtis, is the most mature relationship she’s ever been in. 

A source tells PEOPLE, "Jim's very laid-back, but also focused and driven. He just does things in a very calm way. He brings good energy and this is something Jen loves. Jen can be very Type A and takes on a lot. He's very steady and grounded. He's not a stressed out, high intensity guy and that balance works well for her. There's no drama, no emotional games, or whiplash. In many ways, it's the most mature relationship she's ever been in."

"She took her time getting to know him. She already knew she liked so many things about him before it turned romantic. She was actually a bit hesitant, because she really appreciated him as a friend and wanted to keep him around. But life is short and her friends encouraged her to date him."

"She feels so grateful to share her life with him. She's enjoying every moment. And at this stage, that's enough for her. She's happy with where things are. She isn't really making big plans for the future. She's not chasing anything. She's just incredibly happy, comfortable and proud to be dating him. And they're truly adorable together."

Jim Curtis is sharing how his romance with Jennifer Aniston first started

Appearing on TODAY on Jan. 26, Jim Curtis opened up about his relationship with  Jennifer Aniston and exclusively shared news of his upcoming book, "The Book of Possibility", due out in September.

Curtis told Craig Melvin, "The origin story? We were just introduced by friends. Yeah that’s it, we found out that we had mutual friends, and we started to just chat. It took a long time. We chatted for a long time, and we became close."

He offered a glimpse of what readers can expect from "The Book of Possibility" this fall.

He tells, "The Book of Possibility is a book that is the closest thing to working one-on-one with me. So many people want to work one-on-one with me, I can't see them all, but this book will have guided visualizations that are recorded on a special app, it will have writing assignments, and it has all sorts of stories from clients I've worked with to help inspire people to live a better life." 

Jennifer Aniston is working hard to look great for her rumored wedding

Jennifer Aniston is working hard to look great for her rumored wedding.

Source told Radar Online, "Among their friends, it's widely understood that a wedding is very much on the horizon this year".

"Jennifer and Jim don't shy away from talking about it, and there's a strong belief that they could skip a traditional ceremony altogether – possibly slipping away to elope around her birthday – before hosting a low-key celebration at home for those closest to them".

"She has clearly intensified everything she's doing".

"There's a real sense that she's pushing herself harder than before because she wants to look and feel absolutely perfect standing beside Jim on their wedding day, and that goal is driving just how demanding her schedule has become".

Jennifer Aniston’s boyfriend, Jim Curtis, helped her break out of a rut

Jennifer Aniston’s boyfriend, Jim Curtis, helped her break out of a rut.

Source claims, "It’s only taken a few months, but Jim has completely turned Jen’s world upside down. He’s really forced her to confront the fact that for the last several years, where making The Morning Show was the central obsession of her life, Jen has put herself into a bubble, limited her own horizons and very much became a creature of routine."

"He’s managed to get Jen out of her rut and is actually open to new experiences. The big thing for both of them has been travel, spending more time on the East Coast, and not just relying on Jen’s go-to Mexican vacation hideouts when they need a break."

"Jim’s gotten her to let her guard down and be more open to the kind of adventures she can have when she does".

A source told People, "Nicole spends a lot of time with her girls. She loves family time."

"She's looking ahead to a busy and exciting year professionally too, with several projects coming up."

Jennifer Aniston may consider plastic surgery

Jennifer Aniston may consider plastic surgery because she is afraid of being aging.

A source told RadarOnline, "Total self-acceptance and authenticity are part of Jim's belief system, and surgery doesn't exactly align with that.

"Of course, that's impacting Jen. She's never going to stop wanting to look her best. It's unlikely she'll stop getting injectables completely, although having a partner that compliments her on her natural beauty all the time certainly helps her feel as though she doesn't need them as much."

"But getting no work done whatsoever isn't an option for Aniston, apparently".

"She loves laser treatments; that can do wonders. And there are peptides and biohacking things like red light therapy she is going all-in on."

Meghan Markle wants to get close to Jennifer Aniston through Aniston’s boyfriend, Jim Curtis

Meghan Markle wants to get close to Jennifer Aniston through Aniston’s boyfriend, Jim Curtis. 

Source tells, "He’s the perfect bridge. Jim is clearly looking to expand his platform and reach a wider audience, and Meghan believes she can help with that in a meaningful way."

"Meghan’s convinced there’s a natural alignment there and that working together could be mutually beneficial. But the bigger goal in it all is to get close to Jen."

"The former Suits star “has been trying to get on her radar for years".

"She’s very aware that Jen is selective about who she lets into her world, which is why she’s hit on this idea of approaching her via Jim. Meghan’s genuinely a fan of his work and thinks they could do some great stuff together, so it’s not a total ruse, but everyone knows a friendship with Jen is the endgame here."
