“The Bachelor” Season 21 ended on a high note — Nick Viall proposed to Vanessa Grimaldi, the love of his life. Not everyone in Bachelor Nation is confident in their relationship though.

According to Us Weekly, “The Bachelor” sources say the relationship is already rocky. Nick and Vanessa are both happy, but are in a “volatile” situation.

The publication reports Vanessa’s strong will is attractive to Nick, but it has also created problems. Additionally, the couple are struggling to decide where they’ll live. They said during “After the Final Rose” they were “leaning toward” the United States, but it’s still up in the air.

“They still don’t know,” another source told Us.

Vanessa isn’t the only one stirring things up in the latest “Bachelor” pair. Us reports that Vanessa’s been “incredibly supportive” of Nick’s career path, but she doesn’t want to “be in his shadow.”

“That’s his main focus,” the source said. “He hopes that this [‘Dancing With the Stars’] will give him a shot at lasting fame.”

Questions about Nick and Vanessa’s relationship have been circulating since the “Bachelor” finale. After the episode, the pair appeared on the post-finale special to discuss their future. Bachelor Nation quickly noticed that the spark appeared to be missing from their relationship.

Nick and Vanessa didnt comment on the rumors. They did say they weren't trying to prove anything to anyone, however. Nick and Vanessa haven’t set a wedding date and won't be doing so anytime soon.

Nick will appear on “DWTS” Season 24 starting March 20. It’s not clear whether Vanessa will be there cheering him on.
