It's same situation for me as I live 8000 miles away from my family. I am on day 85 and I became stronger with time. I don't even count the days anymore and only did to write a posy yesterday. Try and do other things and make yourself occupied. You have to give him the space to miss you. It will feel like a win-win situation for you in the end. With time, if he misses you you he will get in touch. If not then you then it was not meant to be but you have already gone through the process of healing yourself.
Please remember that you should be a priority in your life and no one else and consider this to be their loss and not yours'.
