Relationship problems

Normal relationships are always going to have their little tiffs and problems, but it seems like mine has them slightly more often than normal. My guy and me get into little disagreements on a regular basis. We get into arguments over the smallest things that shouldn’t even matter. We love each other so much, but we are so different its hard for us to live together. We recently moved in together and im starting to see things about my boyfriend that I didn’t see before. He is a very messy person although I shouldve known that because most guys in their twenties are. He says hes going to do a lot of things that he never does or he just says hes going to do them over and over again. For example, he has been telling me that he is going to keep the room clean for about a month now. Has it happened? No! as soon as he walks in the door he takes off his shoes in the middle of the floor, strips down to get into the shower and leaves his clothes all over the floor, and never picks up his stuff. I expect him to be tired a lot because of the simple fact that he gets up at 3 am to go to work and he comes home around 2, but it doesn’t make it ok to throw his stuff everywhere. It bugs me because im the one always cleaning up. Im also the one that’s always tripping over his ginormous shoes. Another thing that bugs me is when he takes a shower, he uses a different towel everyday. Ok, now he wants to have sanitary issues. Does he think of who is folding the laundry all the time? No! He also believes that my food is his food no matter who bought it. Uh, no. my food is my food no matter who bought it. If I decide to give you some that’s my choice, not your right as my boyfriend, and I don’t have to say yes to giving you any at all. He also always cuts me off in the middle of my sentences when im talking to talk, or get on the phone. He does uneccessary spending on things he wants instead of things he needs. He will starve for a week because he’ll buy a 400 dollar phone. Things like these bug me so much we get into arguments because I ask him nicely to do something different and he says he will, but he never does. Then he gets upset that im nagging him. Well, I wouldn’t have to nag him if he would just do what I asked him to in the first place.
