I think we ALL know what you're going through, Donna. This is our 4th year of the back-and-forth-across-the-ocean relationship. We spent FOUR YEARS living for each time we were reunited, counting down the days until we were together. And then the second we were in each other's arms, we were faced with the countdown to the day we had to part again. It puts a black cloud over each visit.
This separation is the BIG ONE. We knew it would be this way, and tried to prepare ourselves for it, but it's worse than we imagined. While I sit here in relative comfort, my husband lives in substandard conditions, because there's no work, and no benefits available to help him. I earn a secretary's wage. So after I take care of my mortgage and bills, there's not much left. I worry every day about whether he's eating right, if he's warm, etc. He's a very resilient and optimistic man, which is why I fell in love with him. But I worry, ya know?
It may sound stupid, but maybe instead of thinking what you don't have, think about what you DO have. Although he's far away, you have a man who loves you - a man who waits for you. That's LOVE, Donna. Lesser men would walk away from this. But a man who will wade through this garbage is a keeper!
I'm an expert in surviving the separations.

My methods may not work for you, but I'll suggest them just the same. Break the separation up by weeks. Start looking forward to an event at the end of THIS week, then the next. For me, I look forward to my paycheck every two weeks. Or I'll decide that in 3 weeks, I'm going to do something nice, maybe drive to see some beautiful place, or have a nice dinner out with my mother. Then, you're only looking forward THREE weeks instead of three MONTHS. When you look back, you'll see that 3 weeks have flown by.
I don't know about you, but it's actually easier for me if I don't chat with my husband every day. Chatting for hours on end really gets to me. It seems to make the longing worse, and time stands still.
I know I probably haven't helped much, but just know that we're all in this - we all know what you're going through. There are many, many pillowed soaked with VJ'er tears.
Hang in there. You'll soon be cooking in the Kentucky heat. LOL.
