He is extremely immature isn't he op?
I'm going to change tack, we all know what a bastard he is being and how he is refusing to discuss anything, yes he's being a cunt. There is another post at the moment with some great posts about guilt.
You are right, you are the injured party yet are being subjected to the silent treatment and vicious and hurtful comments of how he does not feel anything for you.
I think he feels a lot ..... guilt and shame when he looks at you and your daughter. I believe he is bullying your daughter into acceting his bad behaviour and for you he wishes for you to forget and not bring anything up so he can return.
The house, the home, the family, your daughter and you are a huge mirror for him to see what he has done wrong. He will not face up to his wrong doing.
I am stating this not to make you accept the situation but to understand it. He is frightening the shit out of you to take control of the situation, whether that is to return with no consequenses or move on with his pride in tact.
I personally do not think he wishes to move on, at the moment. You keep biting and falling into his trap, now imagine that he does still care and still wants you and your daughter, does that make you feel stronger? but he wants you at a cost to you, not him.
I believe he is scared, his biggest fear is you pulling yourself together and delivering him his just desserts.
It's a game to him and he wants to win, drop the rope, stop contacting him and when you are in pain just remember he will be frantic underneath as he is loosing control of both you and your daughter and the situation.
Start eating and looking after yourself and try to stop painfully trying to make sense of him pulling the rug away from your marriage.
Call his bluff, he is feeling shame, his daughter knows what he did, his family and this is causing him to lash out with tantrums and sulking.
Look at what he is, a cry baby who is not adult enough to admit his bad behaviour. Until you understand his weaknesses at the moment will you be able to gather your strength and anger to decide the consequenses and act on them.
Your fear is essential to him to control the situation and the status quo.
Know what he is... tell him you no longer love him and feel nothing more for him. Your strength will return when you stop allowing him to keep kicking you down.
