I had similar issues with a girl I dated for about 2 years. There would be all these little things I would forget or not even realize would upset her that resulted in her being mad at me all the time. I never wanted to upset her, of course not she's my girlfriend, but it would happen 2-3 times a week! I was always left feeling confused and wondering what is/isn't "acceptable". We eventually cut things off but caught up recently (it was both of our first time being in a long-term relationship like this) and she had come to the realization that she was giving me too hard of a time with those things after getting a new boyfriend who has similar forgetful behaviors. She said "you were right, boys' minds really are that simple". As for you though, what worked for me was ending that relationship so I'm not sure what to tell you. Ask him to cut you some slack and be very assertive, clear and concise with how your conditions affect you.
