“Love on the Spectrum” star Connor Tomlinson believes new girlfriend Sarah Siebert may be “the one” after his shocking split from co-star Georgie Harris.

“To find ‘the one’ would be so life-fulfilling. My life would be at a complete full circle,” the reality TV star exclusively told Page Six Wednesday at the Los Angeles launch of clinical psychiatrist Dr. Tamir Aldad’s new book, “Too Close for Comfort: Coping with a Dependent Loved One.”

“And it may be too early to say, but I feel like she may be the one,” he added.

The 27-year-old proudly noted that he’s refusing to date other women after hard-launching his new relationship in July.

“I would politely say to them, ‘Sorry, ladies, but I’m afraid I’m not available,’” he told us.

Tomlinson shared that things with him and Siebert, who is an after-school teacher, are currently “going wonderful,” though they’re “pretty busy during the week.”

“So on weekends or on school holidays, I’m all hers,” he shared.

Tomlinson, a fan-favorite on “Love on the Spectrum,” met and started dating Harris during the third season of the Netflix show.

However, they split off-camera after a Season 4 trip to London, and Harris subsequently revealed she was dating a new man, Luke, in April.

Tomlinson — who announced his departure from the series that same month — admitted that being in the spotlight has “its challenges,” but now that he’s in a new relationship, he feels “happy” living in his “comfort zone.”

Tomlinson also explained how being on TV has boosted his confidence.

“I’m not afraid to take a risk. I’ve gained a lot of great things now, and I’m not afraid to work for them, to earn them, to pull my weight, even if it means pushing past my limits,” he said.

“At first, I was hesitant about sharing my love life with the rest of the world. I didn’t even have the confidence to walk up and ask a woman out, let alone do it on TV.”

“But sometimes a unique opportunity comes your way, and you have the chance to adapt and grow,” the Netflix star continued.

“And if being on ‘Love on the Spectrum’ was the only way I would ever gain the confidence to ask a woman out and be in a legit romantic relationship, so be it.”

“Love on the Spectrum” is streaming on Netflix.
