Horny and Helpless

My boyfriend of 2 months hasn’t wanted to be affectionate towards me or have sex with me in almost a week and a half. He’s been saying that he isn’t in the mood or that he’s tired. I work 2 jobs and just put a deposit down on our new apartment. The only thing I ask for is sex, love and attention. I don’t feel like I’m asking for the world even though I can be a real bitch when he’s lacking in either department. I don’t wanna continue to argue and fuss about the same issues over and over but I believe that we both are under lots of stress and sex should be in our diets to balance it out. I mean who doesn’t love grinding out an enormous orgasm after a long day at work? I’m just really confused about the next steps I should take. I’ve already asked him why he wasn’t freaking on me🙄
