You are such a fixture in the lives of all the people who are lucky enough to really know you,” Musgraves wrote in the Instagram post<\/a>, with photos of the couple’s life together.<\/p>\n “So grateful for all the laughs and adventures, deep talks, ego checks, wise advice, forehead kisses, the books you recommend, your late night ‘oh I just whipped this up’ and somehow it’s extremely gourmet pasta (like, actually Michelin star) situations, the gorgeous way you observe the world and the words that follow. And mostly your unabashed, full-throttle vulnerability which is easily the sexiest thing about you.”<\/p>\n RELATED: Kacey Musgraves Says She Feels ‘Really Lucky’ That Boyfriend Cole Schafer Is ‘So Secure’<\/a><\/strong><\/p>\n The country star, 33, concluded, “I can’t wait to see what this year brings to you.\u00a0XO \ud83e\udd0d”<\/p>\n In December, the “justified” singer shared photos<\/a> of the couple at the Teddy Bear Ball<\/a>, which she created with Schafer in an effort to raise money for the children’s hospital at Vanderbilt.<\/p>\n During a cover story interview with Time<\/a><\/em> in March, when she was honored as one of their 2022 Women of the Year, Musgraves opened up about her relationship. <\/a><\/p>\n Musgraves discussed the lyrics of her song “breadwinner,” and explained that the words certainly don’t reflect her\u00a0bond with Schafer<\/a>, with whom she’s been linked since June.<\/p>\n “I’m not the only one who’s experienced that, and I’m not going to be the last,” she said of singing about a relationship in which the man cannot handle the woman’s success. “It always makes it easier to put vulnerable thoughts out there when you know they’re going to be met with connection.”<\/p>\n Still, the singer said things with Schafer feel different.<\/p>\n
