There are two main reasons that people binge watch on streaming services. I'll explain the first next week. You'll have to wait until May for the second, because I'm taking a break after next week.
Seriously though, unfinished/unresolved/undone things stay on people's minds (Zeigarnik effect). Ironically, you're kind of demonstrating that by saying "this keeps going through my head." You don't have an answer, so you think about it more than if you did, and you're seeking closure. Once you get people's answers, whether you agree with them or not, you probably won't think about it as much. When it comes to TV shows, you seem to enjoy not having the answers immediately - letting each episode soak in and the anticipation - but for many of us, everything that is unresolved builds up in our heads, much like the question of why people binge watch is repeating in yours.
That's why if I can get a few more answers by giving another 42 minutes, I'll do it. (within reason... usually.) Each episode gets me closer to the answers I'm looking for. It's supposed to anyway. I can enjoy something, and once it's done, I can move on.
Regarding blur, sometimes I find that with time between the episodes, I forget some of the points that came up previously. I'd rather watch several episodes so everything flows together without all of it necessarily having to make it into long term memory. I have a feeling that you don't have the problem of forgetting details week to week because you refresh your memory of those points during the breaks as you reflect on what you watched. It's interesting that what you see as blurring everything together is what I see as improving continuity.
I think it's fine that you like to spread out your viewing. You probably get more out of each show than a binge watcher. But for those of us who need to have things resolved in order to let them go, having the next episode immediately available is too fulfilling to walk away from.
