One Summer House couple has gone their separate ways.

Danielle Olivera confirmed she and Cassian Grantboyfriend of two and a half years Robert Sieber are no longer together.

"We broke up in November—it's still hard to say out loud," the Bravo star exclusively told E! News. "It's sad, but I'm finding my happy slowly but surely. I have a lot of really great friends, even the girls on the show. They've been so, so nice to me." 

Despite their split, the tech entrepreneur added that "there's no animosity" between her and Robert.

"There's still a lot of love there and mutual respect, but it just wasn't working out," Danielle continued. "If we can't be happy together, then we have to find our happy separately."

As for the reason for their breakup, the NYC-based reality star credited part of it to Robert's high-demand job as a chef in Aspen, Colorado.

"Our relationship definitely suffered a bit because there wasn't enough time and I would keep things in and then they would obviously explode in the wrong ways," she explained. "I'm not the easiest person to be in a relationship—I am awesome—but I expect a lot also. His career is amazing and I'm so proud of him. Do I wish things were different? Yeah, but that's life."

Danielle revealed she was the first to voice concerns about their relationship.

"I expressed unhappiness and when we got into the conversation, it became like a lot and the bubble burst," she shared. "He was like, 'I can't make you happy right now,' and I was like, 'OK.'"

For now, Danielle wants to enjoy time by herself as she recovers from the split.

"I want to go out and have fun," she said. "I just want to be single for a while. I'm really good at being single, so I'm just going to focus on my career, focus on my app, have fun with my friends and make a ton of mistakes."

Summer House airs Mondays at 9 p.m. on Bravo.
