>>3300558k, dude. i will give you my point of view, might could help you to undestand the problem, or not, anywyas here i go.
1-You ignored him when he even told you "i love you", you was talking with that kiwi, so its not a good begin.
2 and 3- Maybe you both are friends, but if he was a jealous person he could misinterpret
4- When he saw that misinterpret conversation and he saw that you wanted to make a discord for that purposes that probably hurted him even more when you say that:
>i said that i didn't want a discord before.5-This is a support my hypothesis: he is clearly jealous for that things and probably he tough that you was doing weirdshits with the kiwi and his socks.
6-And here you can see how he probably was really bothered about all, and probably he tought that you was doing things with the kiwi for sure.
Bonus: You didnt talked with him until the last moment, (maybe he tought that you was ignoring him) when it was too late, in your defense i must say that he didnt post too much in that thread.
This is my point of view, anyways, goodluck and i hope you find him to solve all.
