hi! did u include a cover letter or did u and your gf wrote a letter to the ECO stating your relationship, how it started and grow? I believe letter from u most especially will help a lot, everything follows then...don't give up, I knew few who were granted who has been refused twice and on their 3rd application were granted as long as you provide answers to their grounds of the refusal and a story about your relationship. I hope this will give u hope...good luck
