I could have just been quiet.
Don't start thinking like this my dear, as soon as you think like that, you will start to drift apart.
Communication is key, and if he doesn't know what is going on in your head, then you will be like every other stranger whose thoughts he doesn't know.
Hurt in this circumstance is (seems) based purely upon the (mis)understanding that has occurred through your communication with each other.
As I have said to my partner, I forgive what you have said, but the hurt cannot, and will not disappear immediately, no matter how hard I try.
This would be useful to remember with your dearly beloved, it doesn't matter how much he adores you, the hurt will still remain, and so that may explain how he is acting right now.
Hurt is as inevitable as triggers, it is based purely on interpretation and understanding, and if neither are maliciously caused, you will not be upset at the person, but rather just focused on dealing with the after effects.
Something I have learnt with my fiance, I usually say to him that; "I'm being bothered by something that just won't get out of my head. It's a difficult topic, so I want to leave it for a bit ."
"If you have questions, feel free to ask, but just understand that it's not something I want to act upon, but something that I want to understand about myself."
"You understand me better than most and can give me insight, but only when you're ready to talk about it."
Anyway, just a thought, I hope you're doing ok, take care, and I hope you keep us updated.
