Hey, Tom! *hugs* It sounds like you had a great weekend with the kids, and yay for cookies!
It's great that you have such a close relationship with the ILs and that they are not giving in to your W's demands for more cash. I'm sure the kids really appreciate being able to still have a close relationship with their grandparents, and I'm sure that removes some stress from them.
I hope your week goes as well as your weekend, and hang in there. You are doing great, and you're an excellent father.
