Let me see..
When he's not with me, I miss holding his hand and talking to him while facing him right before going to sleep. I miss curling up on the couch and watching a movie, or taking our dog for a walk. It's really hard to make food for one person, so that's harder too.
When he's with me, it's the best. We go for walks and just spend hours talking. Now that he's gone, since I have the dog and the cat and the house and work and working out and things that just don't let me talk to him a whole lot at night, since we have a little bit of free time at different times.
Since he's been gone, this has put short-distance LDRs into perspective. I used to think that they were nothing compared to what I was going through, but now I really do count down to every Thurs/Fri. It really does just depend on what kind of distance or time between visits you are used to. It's easier on me since I know this stupid distance ends (again) for us in two weeks and I still see him every weekend.
Sorry, I kind of went off on a tangent, but I think you know what I mean. :)
