hus bday is 3-28-1995 and mine is 10-09-1995.what do you think,are we even as compatible as we think? Emotional expression problems and distance

My boyfriend of two years and I are both boars,but we are opposite in so many ways.the main one being I'm very expressive where as there are people that have gone to school with him for years who have never heard him speak.in about a year I will be off in the military for about 3 yrs...our lack of verbal communication worries me,will we make the distance? I love him and neither of us worries about loyalty but gosh the depredation time...we are both very physical cuddly type people.
