I'm glad your son liked his b'day present. You knew that he would. And he's willing to share it with you. That's great! Time to go fishing! I would love to come out there to some of those big bass lakes and try my hand at catching a 10 pounder. Of course, for your son, any time spent with dad is a good time.
I know you are in a bad spot now. I can't imagine what you are going through. Talk to your A and get things set right. You and your kids deserve so much better.
Remember, your kids need you, not a lot of money for you to spend on them. I know you need the basics like food and stuff to survive. I wish I had some answers for you. Take control back from you W and make it happen.
Tell your son happy b'day for me and give him a big hug from uncle IDU!
