I need to go see me some murals!!!! I know in advance they are beautiful and were created with love, pure love.
I am sorry about your down weekend. I also HOPE you fill your AD's, because its just so hard to come off them abruptly, and you might need them a bit longer.
If I may, I can totally understand your feelings about finances. I am going to be BROKE after divorcing H, struggling monthly. He is walking away with large amounts of cash, and I am walking away with bills. I get very angry about this. And I am not even paying child support, like you are.
I know you will always provide for your sons. And yes, you would help your W (even if she was EX-W) because she is the loving mother of your children.
I agree with Beth (I think she said it), be proactive and let the teachers/doctors/daycare/everyone know that you are to be notified regarding your kids. But honestly, I don't think she did that on purpose (excluded you). I hope not.
Thinking of you, and know you are missing your boys. I am glad they got to see your mom.
