what should I do about my boyfriend?

well I moved in with him without knowing him that much and now I realized that we don't have much in common and I don't really have the confidence to blow him everyday I get too scared to initiate it with himbut he only wants that from me. we get along we like eachother but we also have a lot that's different about us its not like how Imagined I imagined we would have sex all the time but in reality we have sex once a week and the rest of the week blow him and im not even good at it and we don't have similar interests and I still have to pay rent. ill give it a few more months just for the hell of it and then i will probably leave because hes originally from califormia hes probably gonna have to go back at some point. he has manner and hes nice, but he says that he thinks I have the mentality of a teenager he says I don't have good coping mechanisms and he says that since I don't have a good job statistics show that people usually marry in their financial bracket. sometimes he is just a little bit "too" honest with me it causes me to be stand off ish with him like I am scared to reveal too much in front of him because I think hes gonna judge me for it and I don't feel as comfortable as I should feel in a relationship.
