I agree with the suggestion for marriage counseling. I also think you may want to consider the possibility that your DH is addicted to video games, and perhaps look into counseling for just him.
See, it's totally normal to go through periods of time where you don't want to talk to each other or otherwise interact. It's totally normal for those times to primarily happen right when you get home from work. I think lots of people do that.
But spending all of your free time doing something which prevents you from actually taking care of yourself and living your life is truly a problem. Video games can be incredibly engrossing, and I do think people can become addicted to them. My DF has struggled for years to not get sucked into playing games he doesn't even enjoy anymore, and the only thing that's improved the situation is sheer self discipline.
Ultimately, when the two of you are working out an issue, you should expect that you will need to regularly discuss it. That by itself isn't really a bad thing - situations change, people slip back into old habits, whatever. The problem that you're facing is not that you have to keep talking about it - it's that you have to keep talking about it because there has been no net improvement.
To share an example, I really hate housework. I can be kind of lazy about it, too. Because of the way our current jobs work out, DF and I agreed a long time ago that he would do the bulk of the housework (because I work longer hours than he does). However, there were things I was doing that both failed to hold up my end of the bargain, and made it harder for DF to hold up his. That was a problem. I'll be honest - it's still sometimes a problem, because I still hate housework and I'm still tired when I get home from work.
But the reason why it's not a big problem in our relationship (just a minor annoyance we sometimes have to deal with) is because I never slip completely back into my original habits. I have created some new habits that are more in line with a fair division of household labor. And I also recognize, fairly immediately, when something I'm doing is just not fair to my DF.
For instance, when we moved in together, he seriously spent like maybe 1/3 of the day actually doing work. I worked full time. So it made perfect sense for him to do pretty much all the cooking and regular clean-up, and for me to only pitch in on household chores on the weekends. Now, however, DF spends maybe 3/4 of the working day actually doing work, and I'm still working full time. So he probably works about 30 hours a week to my 40. It is no longer fair for me to expect him to take on as much of the housework as he used to, so I've been gradually picking up more of it.
So maybe I have a week or two where I leave all my dishes in the sink for DF to take care of later, but most of the time, I clean up after myself and do some of the necessary household work. A temporary neglect of household work does not, for me, mean that I'm not doing any at all, or that I won't self-correct when I've got more time or more energy.
That, I think, is the goal that you should be working for -- the normal state of affairs in your house should be that your husband does X amount of housework without your having to stand over him and make him. He should only be skipping that housework when there are unusual circumstances in play (like a stressful period of time at work or something). But when those unusual circumstances occur, you shouldn't necessarily be taking over those duties -- ideally, you'd work out between the two of you which were non-essential, and you'd still do the same proportion of essential household tasks.
