Kids back again!!!

The kids are back today and it was like having a part of me returned! They seem to have managed ok but, as expected , despite his promises, he didn't spend any alone time with them. My son says they kissed so much he actually asked them not to in front of the kids. My ex told him to forget it! He amazes me with his selfishness. My doctor has said it is a part of the drinking heavily but it still amazes me. If i could walk away with no more contact it would be wonderful but i know that i need his money at least until the kids have grown up. Then i can be independant of him. I missed the kids way more than i ever thought i could. Hopefully he won't bother again - I think a rainy week in Wales with 4 kids was more than he could stand!!  Now that is out of the way i need to push for something to happen so that i can finally move on. Thanks for the great comments. it is great to know other people are in the same situation.
