Really glad you managed to sleep OP, your whole family are behind you and it sounds like the midwife team are too - you are handling this like an absolute queen.
Your 'D'H on the other hand is absolutely pathetic. What is he hoping to achieve from these messages? I can't understand it at all. Where is the apology, the concern for his children and pregnant wife?
It would be devastating if he said he was definitely leaving for OW and didn't love OP anymore, but would be at least a recognisable human response.
I think he's devoid of normal feeling.
