Hi & welcome shy_gal89 smile

I agree with the above comments and, re studying away, it could be that, as he's leaving, he thinks that it would be unwise or unsuitable to start a relationshiop now. Either of you could meet someone else, without really knowing each other very well.
What do you think?
How long will he be away?
