I'm sure it IS difficult being away from them my friend.

But think about how THEY feel. It's got to be pretty awful for THEM too.
When you're with them, try to concentrate JUST on them. If you can put the house on the back burner, do it -- and just pay attention to the kids. After all, your time with them is limited, and they want your FULL attention.

They deserve it too, because the kids are ALWAYS the ones who get hurt the worse in a divorce.
My daughter and her husband divorced when my granddaughter was 7 years old. She's 17 now, and she's been in therapy for 2 years. She should have been in therapy much sooner, but I didn't have control of her until 2 years ago. My daughter didn't notice she was depressed, and when she came to visit me, she was always happy. But when she came to live with me, she told me she'd been depressed and asked for therapy -- and I immediately put her in. It was all due to the divorce! I knew she missed her Dad, but he'd been a dead beat.

I'm sure that's not the case with you. My point is tho that divorce DOES hurt the children and it can last a LONG time.
Children often times feel guilty about their parents divorcing even tho you tell them time and time again that it's NOT their fault! They think that if they hadn't been born, the two of you would still be married. They think that they are too expensive. They think ALL kinds of terrible things.

You've got your work cut out for you to make sure they KNOW that they are NOT the cause of the divorce!
Like i said, spend all your time with THEM. Put the house on the back burner. they'll love you to death for it. God bless and please take care. Hugs, Lee
