Wow, Mighty! So, he's moving out. X-mass shopping then packing...any idea what hww thinks as to why H is moving out? If she can't understand why you don't like her, she has to be the most clueless, no morals person in the world! Maybe she really doesn't get that sleeping with a married man and getting knocked up isn't a "good thing"?
At this point I really, really think that a DNA test needs to be done as soon as that kid is born. H had a vasectomy and the reversal apparently didn't take before all this started if I remember right. I really have a feeling that your kids may not be having any half-siblings! And if it turns out to not be his, than H can walk away and never look back. I think that's important no matter what happens in your M.
Enjoy mighty! Just be ready for more drama before all this is over!
