Go for it HW!!
Regarding OW - it's all quiet as he's said he won't live with her, she now has this 'back-up' rich bloke who she's now looking to move in with, and in the meantime she is hoping to make H insanely jealous of that, so he'll want her back, and she's making it very clear that she calls the shots with this baby and I'm never seeing it.
She's all quiet as she's working on her plan and I know exactly what she's doing.
The new guy is a meal ticket and a way to push H's buttons. That's very clear and H knows it too. But he's serving a purpose while she works on getting H back.
The minute she gets the slightest hint that H and I may get back together and live together, she will go mental and everything will change. I'll bet my life on it.
And suddenly, rich, supportive, handsome new bloke will be the abuser from hell who is torturing her and will be a threat to her child and she can't possibly do any of it without H as she is now going to be homeless. Of course none of it will be her fault. And she thought this guy loved her. And H's child will suffer forever unless he's there for her and only her... I bet my life I honestly do!
Which is why I've been pushing H so much that if he is genuinely serious about us, then she needs to know. Firstly so we can face the resulting hysterics and blackmail. But secondly, and I believe more importantly, so she realises that if she chooses to bring this child into the world she is doing so with H's full support as a co-parent, but with no expectations of them becoming the perfect family.
