This relationship he has with you is all about his needs. It has zero to do with you. You are simply there to comfort, sex things up, provide cash where needed, be HIS GF and be at HIS beck and call. This relationship will never be about YOU, it will never be US it will always be about him.
After 22 hour shift he should be "hun, rest, love you and speak later. No stress with reply. But no its all about what YOU dare to do in your free time after almost 24 hours of continuous work.
Now, whatever version he showed you the first time you met is a fake, its a made up persona to reel you in. IN future, if you decide to stay, he will display this persona over and over again after each abusive cycle to reel you back in, confuse you, control you and manipulate you into being there for HIM.
Now, seeing he is very controlling, be mindful that you do not feed his ego further, meaning, stay safe when telling him you do not wish to be in this relationship, leaving such a prick is more pain than staying with them as they attempt to control you long after it has ended so stay tough.
You may have to repeat yourself numerous times. Best of luch
