What should I do to feel like I'm a part of his new life?

I’m sure some of you know my history with my bf but just is case you don’t I’ll explain. I’ve been with him for almost 5 years but almost 2 years long distance. Since he’s moved he had no friends so I basically took up a lot of his time on the phone.

Since he joined the army he made a friend. Through her, he made so many friends and they all have their own little circle now and spends a lot of time with them. I don’t know any of them. I met his army friend once when I visited last month.

I feel like he has a new life, new friends, new EVERYTHING and I’m the only OLD thing. I’m just used to knowing everyone and everything in his life and understanding it. I’m so far and I can’t be a part of his new life. I’m introduced to his new life (friends) but I’m not a part of their circle at all.

I just feel left out since he has a life that sounds exciting and changing. I’m just the old gf from his old life…He tells me about his day and includes me in on it. I feel like if I moved I could be a part of his new life but I can’t right now.
