Happy Birthday, Ben Seewald!

The dad-of-two turned 22 years old on Friday, May 19 — and his wife, Jessa Duggar celebrated by writing the sweetest love letter to her husband. She detailed the first milestones of their love story — from the very first moment she saw him to their first date.

“When first I laid eyes on you, a dapper seventeen-year-old young man, I never could've dreamt of what the future held for us,” 24-year-old reminisced in her blog post.

She went on to explain that she was running late for Sunday morning church service when saw Ben — who was visiting from another town — and they had their first conversation afterward. It was a little awkward because Ben decided the best way to break the ice was to ask her about her iPhone. They were apart for three weeks afterward until Ben returned to church and Jessa’s brothers invited him over to the Duggar home. After that, he would take monthly trips to visit and then he decided to transfer schools, which means he’d be closer to Jessa.

But there was one thing that made her doubt whether they could work as a couple — their age difference. Since Jessa is about two-and-a-half years older than he is, she thought to herself, “Surely he wouldn't be interested in an older gal. He's a teenager, and I'm already 20!”

Ben definitely was interested, so much that he asked her father Jim Bob for the permission to enter a courtship with Jessa and then he later asked for her hand in marriage. The couple wed in a 2014 ceremony and nearly three years later, they’re now parents to one-year-old son Spurgeon and three-month-old son Henry.

“There's is just so much more that I could say, but I shall close for now with this: I know that I married up,” she concluded. God has blessed me beyond measure in giving me you! I am so thankful for you!”
