Talk on the phone as much as you guys can..... it really helps.... or even on the computer.

If you can.... get a webcam and then you can sorta see each other sometimes. it won't be the same but it really does help.

I even went so far as to take a picture of myself in the mirror so he could see what I was wearing everyday. LOL it seems silly but it helps you to visualize them when you know what they are wearing and how they look that very day

My husband and I had to be 8 hours apart for about ten months or so. it is very hard..... but if you are both willing to work at it it can be easily done. You will miss each other all the time no matter what you do.... but just remember to make time for each other even if you can't actually see one another.

Also, try to plan trips to see one another when you can.
