Well is he physically capable of helping out around the house now? Then he should be doing that, if you are the breadwinner and working 50 hour weeks, he should do whatever chores he is physically able to, at least leaving you free not to do that.
I almost want to give the advice to you and another poster to get a hobby which I realize is little solution at all to marital problems but the post is so lacking in anything enjoyable. But 50 hour weeks leaves little time, well yes that's why he should do housework etc. if he can to leave you some time for leisure (I know it won't be much but a little). Yea look at your budget, not just for what you can save, I mean that's all well and good, rainy day fund etc., in fact if you can it's probably *crucial* in your situation, but if there is room for something you would enjoy as well (out to eat once in a month if that's it, public transit/uber/cab to go to a free museum once in a while if that's it, whatever you like and actually makes sense for your location etc.). Because you should do some fun things, and yes some might be free (but the lack of transit might be a problem there as a lot of things require a way to get there).
Now people here will probably suggest therapy/counseling etc., but that is going to cost more than any hobbies I suggest. Yes it will cost more even if you have health insurance (good for you if you do, that's important for medical expenses but ...) because unless you really have a gold level gold plated employer plan or something there are copays etc..
As for comparing yourself to your peers etc.. It's a waste of time. Much of it is fate. It's not in our control anyway. I mean I suppose you could have married differently but you probably married for love and not for money, am I right?
