Arguments are difficult and what you describe as issues are the reason he could be melting down. When we say we need space, we need A LOT of space. When we say we need TIME, we need enough time for US to deal with something (not just 'time' to cool down).
We often have to "play out" several scenarios in our head. We also play through different emotions, different thoughts, different ways to relay the information so that you aren't annoyed (which probably won't work).
Talking about things for hours is probably not what he wants, and the longer you drag out a conversation, the harder it is to remain calm, cool and collected. At the first sign of him shutting down, you need to leave him alone and deal with whatever is bothering him; when he's done, he'll re-emerge.
Also, if he is stuck on something you said 4 minutes into the discussion that lasted 4 hours, he's basically "missed" (not his fault) the rest, because he stopped at the first thing that distracted (or hurt) him.
I often shut down in times of stress or anxiety and it can be physically and emotionally exhausting, and I won't want to deal with anyone else (including people or SO I'm close to). You can't change him, you can try to understand. Many people don't understand us, which is why these forums exist, apparently.
