I have been talking to her for a while, she means the world to me. But she goes away for days without telling me what's going on. She's on the other side of the world so I don't know what she could be doing, she could be with another guy, she could be tired of talking to me, I have no clue. but I can't take it anymore and I want to end the relationship. how should I put it? I don't want to sound like a jerk and I still want to be friends. I just can't take this type of a relationship.
