Love is in the air as the Duggars announce that their second daughter Jill, then 22, entered a courtship in November 2013 with 25-year-old Derick Dillard. "I was really impressed with his character," Jill tells PEOPLE. "He's a great guy." Her father, Jim Bob, introduced the two after meeting Dillard via email; the lovebirds got to know each other over Skype and text before she traveled to Nepal, where he was doing missionary work, to meet him – with dad in tow. "I was in love with someone I had never met in person, but we really knew each other well," Jill says of those early months. "I think it could be that I just met my future husband."
