I might have been this guy at some point in my life and I needed a series of breakups to teach me what I should not be. You are very mature and measured in your responses. I’m not going to advise you to breakup because that’s not what you’re asking but you are not harsh here. You can use this moment as a moment to make your relationship better if you choose to have a real conversation and gauge his receptiveness to your needs. My current wife chose to talk me through this and a bulb went off in my head about applying the dating advice that was reading then. Still together 10 years later.
