Your confrontation-style is a bit accusatory, so he's getting defensive because of that instead of having an open conversation with you. You can see that because he never once talked about how he makes you feel, but only looked at himself to justify his actions. Defensive behavior, most likely prompted by your style of confrontation.
In general, he seems to completely disregard that other people may have different expectations or needs than himself, which is also why he doesn't understand why not talking for two days is a problem for you. Cause it's not a problem for him. As long as he doesn't get that into his head, relationships will be very hard with him.
Additionally, he seems to have a lot of other shit going on at the time and wants to be left alone because talking takes up his energy, which he seems to need for other things at the time (like dealing with whatever life throws at him). This is cutting away at his already limited ability to emphasize even further.
On the flip-side, you might legitimately be too "clingy", and on the fence too fast when you don't get an unusually high amount of attention. I don't know how often you talked and for how long, but not talking for a day usually isn't a big deal. Sometimes, people need breaks and that is ok too.
Also, do you know whats going on with him? You didn't ask how he felt either.
Overall, that's a very unfortunate combination. Him with a very low need for sociability, you with a (as it seems) significantly higher need. Judging from this pastebin, both of you don't seem to really be considerate of the other person, which makes resolving issues like that and finding a compromise near impossible.
