Wow that sounds tough, but if it is meant to be, it's meant to be, whether she is deployed or not. See how you go in the coming months in your relationship with her. From a bi mumma to be :)
At least she will be there around the birth time before she leaves
My dad was deployed to korea for a year when I was 4.
I remember him talking to my mom on the phone.
Don't worry she can still talk to you and it passes by pretty quick especially with a new born.
She will be back before you know it.
I would join a military wife support group in your area.
They will help you through so much, especially deployment
Got my Ms mixed, feelin like a dickhead
that's wonderful that you've found the person your ment to be with, that's pretty hard she won't be with you when your baby's born, if you ever need to talk I'm here ok?
