Will Big Sean be "the one" for Ariana?

Astrogirl's resident psychic,Nancy Frederick, says that Cancers like Ariana Grande "will be tempted to ditch a really great boy" by March. Big Sean's already proven he's a sweetie (he stayed by Ariana's side when her grandpa passed away in 2014), so does this mean Ariana will tire of him? "By May, she'll realize that love should be truly romantic," so she'll finally open her heart and see that he's perfect for her. We think they'll go the distance!
