How about this: 'In your arms, I found a strength I never knew I had. I've discovered parts of myself I never knew existed. Your love turned my world upside down, and I wouldn't have it any other way. Without you, my life would be shades of gray. With you, it's a riotous splash of vibrant colors. I love you more than words can say, and I'm incredibly thankful to have you in my life'.
