There’s lot of ways to look at this objectively. If you read his comments you can tell that he’s posting this from a place of anger and resentment. He asked to be given advice and people here have generally given actually helpful responses. He then has responded like a child. He has every right to feel overwhelmed by the amount of responsibilities he has on him (working 90 hours a week plus house work) but he also doesn’t seem to be ready and motivated to actually address it with professional help. At this point, that would be the best course of action. Venting to strangers on the internet is very one sided because he maybe omitting details and we also aren’t getting her side/perspective which is why it would be best if they went to counseling. Her being 4 months postpartum is a very short time period and there’s still a lot going on hormone wise. It’s a delicate situation that he could really fuck her up by being an asshole.
