Jennifer Aniston's boyfriend Jim Curtis feels "blessed" by their relationship.

The 57-year-old Friends actress has been with the 50-year-old author and hypnotherapist for 18 months, and he has opened up about the qualities he admires in his famous partner.

He told The Jamie Kern Lima Show: "It's going really well. My experience of her is so grounded and so open and caring and kind and loving.

"I feel blessed to be in a relationship with someone that is so open-hearted and kind and loving. She uses words like 'my love.' "

Tim revealed he's even been getting on well with her "group of best friends", describing them as "family".

He added: "I feel incredibly blessed to be part [of] and welcomed into that family… such a beautiful community and group of people.

"It really speaks to her -- and them -- that everybody is so grounded, so kind.

"And it's not just to me. There's a reason why that whole group and community is so beloved."

Jim also discussed how the couple deal with disagreements, while still being in the "honeymoon phase" of their relationship.

He explained: "We do a lot of meditation. We do a lot of talk… I think that at different stages in your relationship, that different tools are really beneficial.

"And so, you know, Jen and I have been together a year and a half…in a honeymoon phase, your tools don't have to be like big sledgehammers."

Jim's comments come after a source previously revealed Jennifer is "very happy" with him.

A source told PEOPLE magazinre: "It's a great partnership and makes Jen very happy. Jim's a special guy. Everyone loves his energy."

The Hollywood star - who was previously married to actor Brad Pitt - also feels "confident" with Jim.

Jennifer decided to make their relationship Instagram official because she could see a long-term future with Jim.

An insider previously told the same outlet: "She's comfortable letting people see a bit more of a relationship that feels truly grown-up and good.

"She knows people have always rooted for her to find love, and now that she's in a happy place, she wants to share that."
