Last week's finale, which was filmed six weeks ago in Barbados, saw Matthews choose Khloe Evans over favourite Tabby Richards.
When asked whether his relationship with Evans has a future, Matthews told ITN: "It's hard to tell. Because obviously we finished filming about six weeks ago and I haven't been able to see the winner since then. Very soon, I'll get to see her."
He also spoke of the difficulty in truly getting to know someone in the setting of a reality show.
"It's difficult to develop a proper relationship and be intimate when you are surrounded by people," he said.
However, Evans has reportedly said that she does not want to see Matthews again.
"I don't want anything to do with Spencer now," the Daily Star quotes her as saying. "The show's finished and that's it. I'm single.
"I'm not interested in having a relationship with him. I'm just going to get on with my life. It was unbelievable to win, it felt amazing. But now we're back to reality it doesn't feel great."
Matthews has returned to filming the upcoming fourth series of Made in Chelsea.
He admitted last month that he was disappointed by The Bachelor's low ratings.
