I'm sorry honey. I am grateful that I don't have to go through this but many others do. Maybe find a support group for mommy's who's husband's are deployed or something.
My dad was in the Navy and had to leave for months at a time after my mom had us.
Well look at it positively. You mentioned it will be his last trip so be glad for that. Hope you have a blessed delivery!
So sorry he has to leave so soon after baby arrives. Try to get yourself connected with other new momma friends before he goes. Community is so important when everything is so new. Good luck to you!
This is a very hard situation, you will be fine momma, i was 19 when i had my first child. Was nervous my ex husband was hardly around, trust me you learn. And with no time he will be back.
