Also remember guys you're looking at this from an outside perspective. As in most relationships it's very easy to see what's going on when you have the full breadth of knowledge and awareness of everything but when you're stuck in the actual relationship with someone it becomes significantly harder to see it from an unbiased or outside perspective. You don't have enough distance to see what's happening. That's why there are so many relationships in real life that we can see, or have been in ourselves, where the answer is obvious or pretty clear what to do when you look at it later or as someone not involved but when you are dealing with it often make wrong, dumb or self-hurting decisions. It's really easy for instance to say that someone should leave an abusive relationship with their significant other, because obviously that's what one should do, but it's really hard for people to do it still when they're in it. It doesn't make them stupid for not doing so because it's incredibly complicated to them when it's their relationship and has all of their thoughts and history attached to it.
Was Touma overreacting? Sure was, Tai has no idea what he's going through because he never talks about it. But that's kinda normal isn't it? How many of you are completely open and emotionally vulnerable with your male friends? And if they do something that tromps on your feelings or makes light of your situation or calls you out about something, do you respond coolly and logically with "Well they aren't aware because I didn't talk to them about it so I shouldn't be angry"? You're still gonna get angry.
But yeah we can look at all this and go "Wow, way to blow up on him when he doesn't know any of that" but all this really does is make him more realistic to me honestly.
