"It's been a little frustrating with Ariana," he told Schwartz. "We'll be talking and she just comes at me. That whole girls trip, I wanted to talk to Lala [Kent] about that, and Ariana, she's like, 'What? So you can go yell at women?' And I'm like, 'What the f--- are you talking about?'"
"She's quick to be dismissive of you and that's a slippery slope in a relationship," Schwartz chimed in.
In a confessional, Sandoval continued to voice his concerns.
"It hurts my feelings because the person I love thinks I am dumb or annoying," he said. "It definitely pulls into question whether Ariana and I are right for each other."

"I not only love Ariana but I work on our love," he shared, adding he gets her favorite coffee drink "nearly" every morning because he "know[s] it makes her so happy."

"I have so much more of an appreciation for Raquel, but I just don't know why I am not more attracted to her," he continued, adding that he felt there was "no sexual chemistry" between them.
