I met my girlfriend Daisy four months ago on a dating app. Over time I realized Daisy was extremely reticent about pretty much every facet of her life. Example: I asked her how many siblings she had and she told me she had two siblings, then immediately started peppering me with questions about my siblings. That's what she does. She deflects and redirects people like that and if you're not careful, you won't realize what just happened. I used to think, "wow, she's really interested in me!" But really, it's a smokescreen. When I started to realize I literally knew nothing about her, basic things like what she did for work, her family situation, essentially her whole life history up until we met. I could tell you her favorite books and  TV shows but not much else.

I raised my concerns with her and she basically told me that she doesn't like to talk about that stuff, she moved here to not think about any of it, it was really painful for her to talk about. I was kind of hurt that she didn't trust me enough, or was comfortable enough with me to be open and honest. I told her this. She got pretty offended and told me I, nor anyone else, was entitled to know the personal details of her life as they aren't relevant and I'm over stepping my boundaries. I backed off. I had clearly upset her and I needed to think about what she said and get a second opinion. 

I talked to my buddies about it, or tried to. They joked that she's a Russian spy. They didn't seem to think it was that big of a deal. They've met Daisy and think highly of her. She's witty, smart as hell, kind^andsmokinhot, just an all around fantastic girl in every way. We have similar beliefs, interests, hobbies, the same sense of humor. 

I'm very much tempted to let it go, but I also think it's not weird that someone would want to know basic information about someone they're dating. Am I wrong? I don't suspect her of being up to anything nefarious, I'm taking what she said at face value as I have no reason not to. It's really weird that she knows so much about me and I know next to nothing about her.

I need an impartial opinion: Am I the ahole?
