"You'll never know dear how much I miss you💓" she captioned a beachside snap of the pair

This is … so cute!

This Is Us star Chrissy Metz expressed her appreciationfor her boyfriend, Hal Rosenfeld, in a sweet Instagram post on Wednesday.

The actress shared a photo of the couple — both flashing happy smiles — at the beach, with Metz, 38, resting her hand on Rosenfeld’s chest.

“You’ll never know dear how much I miss you💓” she captioned the beachside snap.

The loving post comes nearly three months after PEOPLE confirmed in November that Metz is dating Rosenfeld, who is a composer.

At the time, the couple was spotted at W Hollywood’s The Living Room for Jazz Night, where they were joined by Metz’s friend and fellow actress Francia Raisa. The group sat in the front row and enjoyed a few drinks and some food while watching the show.

Although Metz and Rosenfeld were only recently confirmed as a couple, the two hadn’t been hiding their relationship. Rosenfeld was on hand to help Metz celebrate her 38th birthday in Palm Springs.

In one Instagram photo, Metz cuddled up to her new man during the festive getaway.

“Reminiscing about one special birthday weekend with a few special people at such a special place,” she captioned the photos shared in early October.

Metz hinted at her relationship with Rosenfeld at the end of October, telling Access Live she was dating someone new.

“I’m socializing with a single person,” she said coyly.

But Metz admitted that she didn’t find her new man overnight. “You’ve got to kiss a lot of frogs to find that prince,” she joked.

In celebration of Thanksgiving, Rosenfeld gave thanks for the special people in his life — including Metz.

“Today and everyday, I’m thankful for a year of great friends, family, work, and life. I’m also thankful to have such an amazing, beautiful, inspiring, loving, and supportive woman in my life,” he captioned an Instagram post of the pair cuddled up. “Happy Thanksgiving, everybody!”
