DO communicate. Talk whenever possible. Fall asleep on the phone together. Skype. Text. Email. Do it, and do it often.

DONT fight. In a LDR, you don't get the luxury of being able to kiss and make up. Fighting puts strain on an already strained relationship. Don't do it. Think about something for 24 hours before you bring it up. If it's important, you'll still be upset. If it's not, chances are you'll forget about it before you can even say anything.

DO enjoy the few times you get to see each other. Treasure them. Don't waste it. Don't bicker, don't get frustrated. Just go with the flow and enjoy the moment.

DO find a hobby for while they're away. Keep yourself busy. It'll make it easier if you keep your schedule packed enough you don't feel the lonely, but not overpacked to the point you don't have time for your other half.

Also...if possible...there is something that my hubby and I have always done that I think would help every LDR if they did...

Before he leaves, and every time he left after visiting, we both wrote notes. Nothing deep, just little "I love yous" and "I miss yous". He hid the ones he wrote all over my house, so that I could find them randomly throughout the time of our separation. I hid the ones I wrote all over his bags and belongings. Tucked into jacket pockets, snuck into his wallet, hidden in his laptop bag, stuck it to his mouse so that it wouldn't work and he'd have to turn it over and see the note, etc.
