<human>: Bf of 3 years is in the middle of studying for his exams... Last night I stayed up late to be his "alarm" clock so I can call him every few hours to wake him up for a nap then study then nap then study. I went to sleep at 5am pretty exhausted and I guess while I was sleeping he called me at 8am and complained that the subway is delayed and he's gonna miss his exam.

I was pretty freaking tired so I was half asleep, I said "babe im playing league of legends bye" and I hung up. Only I wasn't.. I didn't even play last night. I just said that while sleep talking. I called him 7 hours later when I woke up and I had no recollection of what happened this morning. I asked him how was his exam and stuff and he was telling me what happened then he said okay sweet revenge time and he hung up on me while I was talking. I was frazzled and confused, wtf?

I then figured out what happened this morning and I told him on facebook and he said this to me: I was in a dilemma when I needed you the most and you left me. 

I said sorry of course and explained what happened again and he just didn't respond back to me lol. I was pretty upset and hurt that he reacted that way.. Few hours later he responds back saying he was never mad its not a big deal but I still feel hurt over it? Am I just over reacting? I told him I still felt hurt and I care about him a lot but he said "if you did this to me I wouldn't really care". -_- so confused

Could you distill the essence of the text into 1-3 sentences?
