My DH and I are a bit different. We never had an LDR when dating but we are moving to the US and because of timings with jobs and immigration, we find ourselves in an LDR for the next couple of months.
The things keeping us sane:
-video skype
-lots of chit chatty emails - we try to talk about the mundane and little things, as it keeps us involved in the day to day
- pics of silly things and goings on, like our new flat as I am unpacking
- definitely living life - going out with friends, seeing new things, etc.
- keeping busy -DH in particular is doing tons of travel with work
- shopping and other creature comforts - there is something to be said for treating yourself when you are down.
