Aww - I'm sorry you're upset! I have no earth-shattering status update LOL - just got the email saying they've received my application...perhaps he was making reference to someone else? In any case, while I'm not an expert, I don't believe whether my husband travelled outside of Jamaica or not would bear much weight in this process..perhaps moreso if it was a visitor visa application.
My husband and I were pretty young when we started dating too - I was fresh out of university at the age of 20/21. I'm sure with 7 years of history you have a lot more paper trail than I do! Keep your head high hun - if you need to chat we're here
