Intimacy

My boyfriend and I had a very intimate moment this weekend and it was the best thing I have ever experienced. I'm not talking about sex, this weekend we just laid down and talked about our past and we learned more about each other. I felt like it was something special that no one could see but us. The only problem was that I didn't tell him much of anything from my childhood. I feel like if I do tell him anything then he will look at me differently than he does now. He says he loves me and that I make him happy and that he isn't going anywhere, but in my life all I've experienced is people saying they aren't going anywhere and that they'll always be there for me and the next day they are gone only to be seen as a memory. I don't want to be seen as a sob story,seeing as I am a very emotional person. MY QUESTION IS: Do I let go,once more, and put all of my trust into him and let him see me naked, not physically, but spiritually for the person I am? It's hard to trust so easily when you've done it so much and have been let down.
