Tristan Thompson and Khloé Kardashian will be spending a lot of time together in the coming weeks as they try to celebrate the holidays harmoniously for their child — but that doesn’t mean the pair will be rekindling their romance.

Despite Thompson’s best efforts to romantically reunite with his ex, a source close to the Keeping Up with the Kardashians star tells PEOPLE that Kardashian, 35, is not interested and continues to move forward for the sake of their 19-month-old daughter True. “It’s hard not to admire Khloé,” the source says of Thompson, 28, and his mindset. “She decided that she was going to be in a good place with Tristan, because of True and she really is. She refuses to be bitter and dwell on the past.”

“Tristan still tries to date her, but she doesn’t seem interested,” the source continues. “She seems very happy the way things are. She loves just being a mom and focusing on work.”

As of late, Thompson has been putting in a valiant effort to mend his relationship with Kardashian following his cheating scandal in February with longtime family friend Jordyn Woods. Last week, Kardashian showed off a pink balloon arrangement that Thompson had sent her as a gift after the launch of her new pink diamond KKW Fragrance. The balloons spelled out the name of her new scent. “Today was the launch of my pink diamond collection with KKW Fragrance and I got these balloons sent to me from baby True and Tristan and I really appreciate the love and the thoughtfulness,” Kardashian said in the clip. The mother of one then noted how proud she is of her and Thompson’s ability to come together for the sake of their daughter.

“I’m really proud at the co-parenting place that we are in,” Kardashian added.
