Innocent Questions

It seems to me like I can't talk to him or ask him about certain things anymore. He always thinks that Im complaining or accusing him of something. Im really not. Sometimes I am but the majority of the time, it's completely innocent and I have no agenda behind it. It just comes up in conversation and I become curious and so I ask. But that's it, nothing more. In a way it is my fault that he feels that way because, I did that alot in the beginning and I did always think there was something more going on. Yes, I do have some insecurities, who doesnt? But when I do have a question that has to do with an insecurity, I specificly let him know. But the rest of the time it's just something that comes up and I get curious so I ask just to know how he feels about something or how he is about some things. I'm not looking to make a conversation out of it, just a simple and clear answer and thats it. My nature has always been very curious, very nosy. I like to know everything. I like to ask alot of questions. I don't know why, it's just who I am, and most of the time I don't see any harm in it.
But know I feel like I need to start being more careful about certain things I talk about or bring up. I have to be more careful about what questions I may want to ask. I don't want to be upsetting him. But I also want him to understand that they are just silly questions that don't mean anything.
I wanna make him happy and I don't want to loose him over something silly and frivolous. But at the same time my quirks make me who I am. In order to have a balance what things should I give up and more importantly how much?
I don't really know what I should do. He's not only my significant other but also my best friend and confidant. My girlfriends live in another state. I don't really have anyone out here except for him, if I can't talk to him about certain things, who else can I talk to?
I love him, I love him to death. I just want to try to make him as happy as I can. I want him to be happy with me. I want to be good enough for him, and sometimes I don't feel like I am. He doesn't make me feel that way, I just feel like I'm not good enough. Like there is someone out there that is so much better for him. But I know how he feels. I know he feels that I'm the best thing. And honestly that helps a little.
