A beautiful man, inside and out who makes you feel like the most special person in the world. He is very intelligent and thinks about others. He puts the ones he loves before himself and is always up for a good conversation. If you meet a Jack, you will most definitely fall for him!

I didn't mean to fall in love with Jack, he's just amazing!
