You hate it, but it's happened – love of your life has to travel abroad. Will it be days, weeks, or even months before you'll see them again? Many people have had to face this situation, and what many of them never consider is ways in which it can make your relationship stronger.
Sure, you lose physical closeness, and that's a hard blow to handle. But you can also focus on other aspects of your relationship without distractions. When is last time you've had a deep conversation with your lover? Maybe even discussing your desires, fantasies, and ambitions?
The saying 'Distance makes heart grow fonder' is true in many ways. In a long term relationship, sometimes you find yourself wishing you could get some time to yourself. The commitments of a family, job, and other things that life throws at you can sometimes make this impossible.
Taking time that your lover is away to not only improve your communication between two of you, but to also improve yourself, can make a huge difference in your relationship and life.
If you've always wanted to get fit, take up a new hobby, or just change track your life is headed on, time while your lover is away is a good chance to take to do so. Just think how thrilled they would be to come home and see you healthy, or having fun with a new hobby. It would also help to take their mind off worrying that you might cheat.
You will need to focus on relationship as well, but in ways different from what you have done normally. Since you won't have physical closeness, you will have to find other ways in which to compensate for distance. Nightly phone calls, talking over voice chat software, or seeing each other on web cams can help alleviate this a lot. I'm sure you can think of some other fun things to do over those too!
