I am so sorry to hear that you had to go through that. I think that the cold unspoken words are harder to handle then if he was yelling and screaming. I don't think that this episode should be ignored like it never happend. It's coming from somewhere and you should ask him to open up about what even drove him to feel that way. A lot of times in a marriage people might feel like they want to give up because that is easier then working on it and most of the times they don't mean it. I hope that all turns out well. Good luck and hang in there. Major hugs your way!!
