We have a long distance marriage.
My husband is in the forces, and we don't live near his base so he travels home at weekends, or he is away for weeks and months at a time.
It's been like that since we met, he would come home at weekends, and he met me at a friend's house when he came home one weekend and his parents had gone on holiday without telling him. He couldn't get into their house so went to see his best friend (who was living with my best friend) to ask if he could stay with them for the night, and I was there. We got talking and it felt like we would never run out of things to say.
He asked if he could call me during the week, I didn't expect him to call but he did, and that was the start of our long distance relationship.
We even had a long distance marriage proposal, by accident over the telephone, and had to wait five days to see each other afterwards. We were married seventeen weeks later, and in that seventeen weeks he was sent away for several weeks, we both came down with chicken pox, and we only had weekends to organise things, but it was a lot of fun all the same.
Three weeks after we got married, we moved into our married quarter, and two days later he was sent abroad for six months.
Even when he was back, he wasn't always based where our married quarter was, and our relationship was still long distance, so we eventually bought a house in our home town and now he travels to and from home from wherever he is based.
It's worked for us for fifteen years now, we make it work with lots of phone calls, texts, emails, Facebook, notes left in work bags, even chalked messages on the kitchen wall (if he leaves while we are sleeping there's often a heart or a message drawn on the blackboard wall for us to wake up to).
I think having to live long distance makes us appreciate the time we have together more and more. It's not easy, and it's not for everybody, but if you have love and trust then you make it work and it can be a lot of fun.
