Tayshia AdamsandZac Clark’s breakup doesn’t come as a total surprise to their friends, a source tells PEOPLE.

According to the source, those close to Adams, 31, and Clark, 37, “didn’t see them getting to a wedding.”

“Things have been strained through the fall. Both of their schedules have been really tough,” the source says of Adams, who has been co-hostingThe Bachelorette, and Clark, who is the co-founder ofRelease Recovery, an addiction treatment center and transitional living facility. “Tayshia hasbeen very busyand Zac also has a lot on his plate. Scheduling time together was just very difficult.”

“She’s also way more comfortable in the spotlight because of her job and he’s much less so,” the source continues. “At the end of the day, they’re very different people. They’re both good people — she’s amazing and he’s a great guy andvery passionate about his work. But they’re a total mismatch.”

But there’s no timeline. It’s definitely going to happen. I just don’t know when.”
