Krystian’s comment about Jon and Rachel Bear read, “This fairytale is beautiful. You two have the kind of love us mere mortals only dream of.” Jon continued his emotional post by reflecting on how time is fleeting, and by showing his appreciation for Krystian. “None of us know how long we have left so make today, because this could be your last chance,” he concluded. “Thank you my friend for supporting us from the beginning.”

“He only has one photo. Please give it love and a comment if you believe in true love,” Jon asked his followers. Fans are watching Jon and Rachel’s love story unfold on Season 2 of 90 Day Fiancé: Before the 90 Days, and they’ve already become enamored with the pair. The two met through a social media app and even though Rachel later found out she was pregnant with her ex’s baby, she and Jon made their long-distance relationship work since they reportedly got married! Here’s to hoping this next chapter of life is nothing short of magical.
