Hello Vani
Long-distance relationships can be difficult at the best of times.
If there are problems, then the distance could make them worse.
In the 8 months that you have been dating, have you been able to spend much time together?
Does he say that he loves you?
Or does he want a 'safe' relationship that does not involve love?
In my own personal opinion, relationships will last where there is love, trust, closeness and friendship. I think that all of these are needed.
Do you really, deeply love each other?
Do you trust each other?
Are you close ~ able to tell each other anything & everything?
Are you also good, close friends?
Of course, after only 8 months, and living in different cities, you may not yet have reached the point where you can easily answer these questions, but what are your feelings on the matter?
Do you love him / feel that you are falling in love with him?
Does he feel this way?
What do you actually
want to do?
Perhaps you just need to spend a little more time together, talk things over and see how things evolve.
And, as BLR says, in time it may not be you who moves on ~ it may be him.
Good luck
