Camila Cabello got candid about her relationship with Shawn Mendes in a note shared with her fans Saturday night (Nov. 28).

“I’ve learned a lot about love with this guy,” Cabello wrote about her boyfriend on Instagram. “It’s not just the happy blissful moments you see in pictures and videos- When you’re in a relationship with someone, it feels like they are this mirror reflecting yourself back to you- I constantly have to confront my fears, my anxieties, my insecurities, my patterns of thinking, my beliefs about life and about myself.”

She continued: “It’s not as simple as it looks in pictures sometimes. sometimes, it’s messy and uncomfortable and ugly lol. But there’s nothing like the pull, the FORCE that is love, to be the light in the darkness- to be the gravitational pull that gives you the relentless strength to be braver,wiser, and better than you were yesterday.”

“It’s so instinctive for us to love,” wrote Cabello, “even if our minds try to protect us from it sometimes, but our nature as humans is to love. And to be in love means to choose that person over and over again, to go through the messy stuff with. And that’s way more beautiful and raw and real than perfection.”

The singer went on to explain why she’s willing to speak so openly to her fans.

“I’m all for being vulnerable on social media because I think only the neatness and perfection of life is shown on here; and that can make us all feel extra lonely and weird! So raise your glass to the messiness and weirdness of being human and the miracle. And the easiness. And the instinct. And the relentless force that is love.”

Mendes recently spoke of Cabello being a calming presence in his life.

“For seven years, I was on such a speedy path down one way with blinders on, and I wasn’t keeping in touch with my family and friends,” he said. “But when I landed with Camila, immediately she had her family around more. [She’s] all about the family and friends, and it really made me like, ‘Oh, I should call my mom’ … I felt a little bit alone out there and she changed that for me.”
