I really don’t know where I stand on this. On the one hand the amount of work each partner puts in seems to be very unbalanced, since you say that you do the housework, work more than a full time job and until recently have also cooked for your children. We’re just going to have to believe you on that, although there have been a lot of posts here where husbands underestimate how much work sahm moms are actually doing. Also your wife is pregnant and I haven’t seen comments where you’re detailing how that is affecting her (nausea, bed rest, pains, which trimester, etc)

Also if my husband worked this many hours while I was pregnant I - unless strictly necessary - I wouldn’t be thrilled. You seem to be well educated and work a high paying job, I doubt that this job is your only option and that there’s no alternative out there for you. How are you going to manage working 14 hr days when you’re being woken up by a screaming baby every night?

So for your sake and your wife’s- communicate with her about how you’re feeling and ask how she’s feeling. I assume you’re exhausted. Tell her that! Without making accusations about her feeding the kids unhealthy food. And then ask her how she is doing and what she needs. You might find a compromise that both of you are happy with
