My t and i have been in different countries for 3/4 of the time we have known each other and its hard. We have made recordable story books together when we were together, made some silly photos and videos of us together (like when we went bike riding together), and T also has made me several you tube videos so i can see her face.
It helps, a little.
Its not the same as her being around, shes rarely here in my country, so theres no chance i can get dependent on her.
