Cannot concentrate

So close to rent and util and phone bill and I'm home, trying to study or do something at all productive after a failed attempt to pick up a shift at hooters tonight. I need the money for rent, and I need something to take my mind off my useless boyfriend. He snapped at me last night and never apologized for it, and i'm supposed to just let it go and be fine with his sarcastic apology, but I'm not. It still hurt my feelings and all I really needed was a sincere real apology and this would be over right now. He blames me for dragging it out when he is the one dragging it out by not just giving a sincere heartfelt I'm sorry. He had to go and make a big deal out of it, and tells me "I did say I'm sorry, you just didn't accept it." This is so not fair, its not my fault and I still feel bad even though I didn't do anything wrong. Its not right at all for him to treat me like this, I didn't do anything wrong and for him to make me suffer and wait up so he will go to bed so I can relax and go to bed as well is wrong. I shouldn't have to wait up and be upset and anxious and feel bad, he should be the one feeling bad but he isn't, and then he turns it against me. Its not right, and I don't want to be with someone who does this everytime he does something wrong. Its going to happen, because no one is perfect, so this is obviously going to be an ongoing problem if he cannot apologize and admit when he is wrong. We've had a serious fight over this before and we talked. I said something had to change or this was not going to work. He told me it would and we had to give it another chance to even tell if things could change. Well here is fight number one, the tell all- and guess what!? nothing has changed, mr I'm always right and you can't lecture me about anything because i never do anything wrong is at it again. Now I'm concentrating on how much I'm annoyed with him and I can't get through any of my studying, and I can't go out and do anything because I feel like shit. I just don't want to have to deal with this. He is so great in so many ways but this is a huge problem we are going to keep having and I have to decide if it's really worth my time.
