ok as u now am in navy, well i have a month leave starting when im home in morning

and ive been with the same girl for 3 n half year n i love her so much
she is the most beautiful person in the world in my eyes n so i wana purpose to her
yh u might think its rushed but we've talking about it since i knew i was going in navy

but my problem is i lack in the romantic department

any advice how i should do it?

Well, it is a very messed up situation, one that I can actually understand. My buddy's with a long-distance relationship with his GF. But their case is more eff'd up - they're both in the Navy, but in separate fleets.

Try buying a webcam and keep in touch as long as possible. Maintaining a long-distance relationship is going to be a LOT of fucking work.

What Rezzy said and get her a diamond. Remember, girls love diamonds.

Oh, and remember important dates and things (Birthdays, Anniversaries, favorite color, candy, etc.).
