Spend half your life in the post office and the remainder on the phone using up his welfare minutes! lol
In all seriousness its tough, but its possible, its impossible to imagine what they have to go through unless you have seen it yourself, luckily before i married a soldier i was a soldier so that helped me out a bit on the what they go through stakes.
You will have good days, bad days and worse days, bad days seeing them leave, goos days seeing them return and worse days in the middle waiting and counting the days, but write,e mail and just keep counting, try and avoid any gossip it will only worry you more if you hear the other wives chatting rubbish.
The little things amke the difference, i remember mine going off and how sad i felt he was going to miss the birth of our first child but it was also excellent watching him see his son for the first time on leave.
Take the good with the bad, remembering the good makes you stronger.
Stick at it babe
Youll be great x
