Of course you are tired, taking care of kids is hard work. Vent here, H's would probably assume guilt and not take the venting as what it is, would assume criticsm (though there is some there, not the main point) and do damage, but do get it out, you need to. It is healthy for you.
The fearful side is hard to let go, but that is something to strive for. I, too, don't understand how they can be willing to miss out on so much with the kids, but that is their burden to bear, we can't assume that. We need to leave that to them and God.
I know how much it hurts when they say the mean things to us and want their daddy. You are right, it is their verbal and processing skills at work, trying to understand all this. I hate it, I want to defend myself, but as with my H, I know defending will do no good, especially with the kids. It is easy to see that, why can't I with H?
Keep working on the goals--I'm planning to steal your when they are done! LOL. Need to get my lazy butt going on mine.
And when he gets home, don't forget to act as if he is as overjoyed to be there as you are--remember the example Michelle uses in the DR book? Keep it in your mind and enjoy!
