Are newlyweds really this sickening sweet?

My friend got married a month ago. Her and her husband are just all I love you. You're my best friend. You're the best wife/husband in the world. You're my universe. They've been together for almost two years, lived together for a year. They were like this before they got married and it's kind of driving me crazy to hear I love you every five seconds when I'm around them. And every time we are hanging out and she's away from him their texting each other. So their always in contact. Will it ever stop?
