OMG, that prick is the last person the OP should be concerned about!!! Let the bastard look out for himself like he's been doing for the last year!! His actions are on him, and him alone!
@Waffletots like everyone else I've been so impressed by the dignified way you have dealt with this. You're a very astute lady - you thought quickly and decisively within the matter of hours and you could not have handled the situation better. Dark times will lie ahead, we all know that, but always remember that you are amazing!
I am totally disgusted that the cunt hasn't even asked how you, his wife who's about to give birth imminently, and his child, are doing. He has blasted the biggest bombshell into your lives and he isn't even man enough to express concern. That only heaps up on top of his awful betrayal.
Do not contact him - leave that ball in his court! He's playing tactics here and he has an utter fucking nerve on him! Do not tell him you've gone into labour. Someone can let him know once the baby is born. He doesn't deserve the privilege of being at the birth and you don't have to look at his rotten cheating face.
I'm glad you have such a good family to rely on. Take care x
