What is your question?
Long distance relationships come about for all different kind of reasons.
The question is, why do people choose to have them?
Have you chosen to carry on in this relationship because:
You think he will come back? If he is going to come back - do you treasure your relationship enough to wait.
You are planning on going to stay with/live with him? If so, what are you waiting for/do you appreciate your relationship enough until you can/does he want you to go?
Are you doubting continuing this long distance relationship because you don´t know if you will be seeing eachother again. Then find out - talk to him/ask him.
If you plan to continue this longdistance relationship with such distance between you both then the question is different: What do I want out of a relationship and can a longdistance relationship (this is not to do with youself and him) give me what I want?
