While every relationship has its ups and downs, there seems to be something a bit deeper here, perhaps counseling would be best! I hope everything works out!

Well, if he behaves like this maybe he has a problem. You don't spend all of your time complaining or criticizing if you are happy with your life (and I must guess this isn't his nature, otherwise you wouldn't be posting this). As his mate you should try to understand what's wrong, not dismiss him. However, it may be that you tried and he wouldn't listen. If that's the case than you probably have a bigger problem

In all honestly sounds like he is sexually frustrated maybe you guys should plan a date night together (please plan together so that both your interest are met) and see where it leads.

At least he makes an effort to talk to you which is a lot more then some people get, (not a personal reference mind you). Is his stories at least funny?

Sounds like my dad. Leave whilst you can, it won't get any better.

when your comment is a vague stereotype comment like "everything" and "for months" you are dismissive and likely not listening to much he says..many people bond and chat about common dislikes like politics, traffic , work etc..etc . if he is not worth your time to just listen and comment and maybe steer the conversation to somthing more mutually interesting, then you should rethink your relationship. ...communication is key in a marriage.

How about instead of dismissing his criticism, you listen to him, have a conversation with him, and see if you can solve some of the problems together. My experience has shown that neither partners are free of faults, and both need to work hard to make the other happy.

I'm going through the same problem right now and I would be your husband ??? I don't know why I'm being like this but I'm not happy ... it's just comfortable !!!

i just got out of a 10+ year relationship and that was one of the reasons I left

No idea why almost everyone is blaming you, OP, for getting worn down by someone who is constantly critical and negative. I only hope you explained to your husband what you did to us, and that you were both willing to try to change the situation. Good luck with it!
