Go to gym, work more, keep yourself busy, study, go shopping, take care of urself (nails, hair, hygiene, body etc.), go out with friends and stay positive. It takes time, but all the good things in life take time.. I've been away from mah bf for 2 years now and yeah, we talk every day and every night.. but I'm dying to see him. I'm staying positive, and I know one day i'll be able to see him!
Just write letters back and forth. My brother joined up and that's how we kept in touch.
Prayer. Pray so he will call you sooner. Pray for him.. so you could be in his heart forever.
By living life.
