It's hard because you are not detached enough. It's the coaster ride from hell. We've all experienced it. You think that you are on solid ground and bam! They are at it again. He wants to discuss child support issues again, if you have a lawyer, you may want to direct your h to him/her. How many times do you need to discuss child support issues? Could it be that he wants to beat you down until you agree w/everything that he wants? A lot of them will do this.
You have control over your emotional state, do not allow him to dish out misery to ruin your day. He's a miserable, selfish little boy right now and he doesn't want "mommy" to have any fun. If he's feeling miserable, why can't "mommy" feel miserable too? After all, in his eyes "mommy" is the reason he is so unhappy. Not, true.....just remember, you have nothing to fear, but fear itself.

Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
