I am done with this nonsense!!!!

So I go out tonight and have a perfectly good time. I worked overtime all week so this weekend I could go to see Dave Matthews which I have done every year for the past ten years. I come home to my boyfriend picking a fight with me because he said I didn't do anything for his birthday. Now I totally would have done something except he got fired from 2 different jobs in less than a month and I have to work to pay the rent. So sorry I didn't have money to buy you a video game or take you to dinner when I have been barely eating myself. We even agreed that we would do something once we got caught up on bills. and I have been secretly planning something for next month so he wouldn't feel like I forgot. But because I haven't mentioned to him what I'm planning he assumes its nothing and acts like a dick. Throwing in my face how he helped me this year Which happens quite frequently when I was getting off pain meds and doing something better for myself...I thought. Now I don't want to do shit for his birthday. For someone that has no ambition and barely ever gives me any affection he expects me to act like a doting, loving girlfriend. Well that went out the window a few years ago. We have been together nearly 10 years and this is obviously going nowhere slow. Basically we are roomates. This is not the relationship I wanted needless to say not the one I dreamed of, it is simply NOT a healthy relationship. I need to just get off my ass and end it. I have options if I apply myself, I think I could go farther in my life if I wasn't worried about making HIM feel emasculated. Fuck him he didn't worry about me when he said I was annoying because I wanted an answer to my question or for him to just explain himself plus the countless other hurtful things he said. He says whatever he wants having no remorse and having no regard for how it may make me feel. Maybe I should start throwing low blows like he can barely get it up and when he does it only lasts a few mins "If i'm lucky". If he goes down on me its like watching paint dry. I could finish myself off easier and not have to worry about him poking around down there like hes looking for his house keys. I would say car keys but he doesn't even drive. I might as well be alone cause I am just as lonely and not even close to being fulfilled. I don't even feel the love I once did. This relationship is pointless. I've been losing weight not that he says it bothers him but the sex im not getting makes me think otherwise. I am just sick of it all. I could be single and then I could at least have random sex or at least have an excuse not to have sex. If I don't get some physical contact soon I don't know what I'm going to do. HELP!!!!! I am not saying I'm perfect in any way but I am a kind person, I tell it like it is, I respect my fellow human being, and I have lots of great qualities that I'm sure someone would appreciate. Why am I wasting my time on someone that refuses to grow up and treat me like I'm never going anywhere???? I know what to do but the follow through seems impossible.
