I thought it was clear OPs attitude toward the menopause, that I and others have commented on, so that was in response, as it didnt sound [in OP's words] the way you say it. It didn't sound atall like anything was managed or worked through together. It came across like he'd already had enough of her mood swings and then she cheated.
Nothing he's written suggests that this is the case. You and a few other posters chose to interpret it this way because of your own sexist agenda. A quick advance search will show you the OP's previous post on this and give some insight into why he's utterly fed up with her. Though even if this was his only thread, he's posting on an anonymous forum looking for support and is just as entitled as any woman who posts here to vent about his cheating spouse. On many threads where a cheating husband has had a mental illness, posters are tripping over each other to tell the OP that 'he's not depressed, he's a selfish bastard'.
But OP is not engaging with his own thread effectively in terms of supplying infortand has decided, against all advice so far, that he will ignore her, as he has been for 4 days.
How childish, punishing, and unlikely is that to sort anything out?
She has done and he's every right to call time as a result, but he's not, is he
He's moving out of their home as soon as an alternative place is available and he's after a fair split of their assets so it really does not sound like he's trying to punish her. What's more likely is that he's fed up, hurt and disgusted with her behaviour and understandably doesn't want to interact with her. He's said he does plan on telling her and will tell her when their tenant comes back from her holiday. No idea why that is but he can handle this and tell her whenever he feels ready. We all deal with things in different ways and it's ridiculous to expect him to rush himself and work on a timeline that best suits her and protects her feelings.
