It could be that what seems minor to you isn't minor to him, it could be that he is trying so hard to be accurate in describing what he feels that he doesn't think about how it makes you feel, or maybe he's a narcissist who takes every little thing as a personal affront. It's hard to say. At the end of the day, if you're 5 years into your relationship, and he's treating you that way, it's probably not going to change.

About your profile, and what you're saying about it, it sounds like your needs are not being met through your relationship. As someone whose needs aren't met in their relationship, I can say the longer it goes on, the harder it becomes to leave, and the more the inadequate aspects of the relationship become normalized.
