ah yes, I remember the "don't rock the boat" period. Heck, it was just four or five months ago for me. Then the government did what it does, and child support started to be deducted from his paycheck. He hadn't seen our child for 7 months by then, so I was nervous that he'd show up and make demands.
Turns out nothing much happened. He made more vague email threats, and then he did the predictable thing: he quit his job. And since then, he's faded away. He stupidly posted his new job/title on LinkedIn, but perhaps it's a flub...who knows.
Like you, I'm not pushing the issue. I assume he'll figure out how to evade the government for a few years, or maybe forever...until babymama #3 catches up to him, because I know for a fact that she's gunning for him, for a good 10K.
*hugs* to you. I know it's a stressful time. Try to remember HP is at the wheel and that you're in good hands.
