I've been dating this girl for three months that I connect with in a really unique way and I want to be able to create a foundation for a strong LTR. So far, I'm really hopeful about how things are going: She's really mature, she doesn't play games, when she has an issue we discuss it and come to an efficient solution with no drama, sex life good, she pays for all her own shit, we are both really physically affectionate and love oral sex, and the thing she likes the most about me is my intelligence, which is inherent to my being. She's also the hottest girl I've ever been with and she told me she loved me when we were really drunk. I haven't said it back yet because I'm not ready and she's been respectful of that.

Here's my concern: she's fascinated by my brain and constantly asks me questions about what I am thinking, trying to uncover my secrets and insecurities, trying to get me to "open up" to her, per se. I know this can be dangerous based on TRP theory because women like to leave things to the imagination and "figure out" their man by themselves, but I'm finding it really difficult not to divulge to her. This is because she keeps opening up to me, and her story growing up is so similar to mine that I relate to it more than anyone I've ever met. This is not me exaggerating or idealizing it. We're actually that similar. Keep in mind I haven't told her much about myself so there's no possibility of her making this stuff up to appear similar to me.

Here's my question: How much should I divulge to her? I was emotionally/physically abused as a child by a mother with borderline personality disorder so I have a lot to potentially share. Should I hint at information about my past and how I feel, should I divulge stuff every once in a while over a long period of time to keep her interested or should I not share anything at all? If I don't share things with her or limit how much I share, how do I do this in a way that won't distance her or make her feel rejected? I externalize my thoughts a lot by habit and she has already expressed feeling rejected when I don't elaborate on them.
