Why do I find it so difficult to open up and tell my boyfriend everything that's happened in my life? He's told me everything about himself but my past is too shameful, I only told him the important stuff, but he wants every little detail. I want to tell him, but its so hard to talk to him without crying and he tells me that if I really wanted to be open with him, I wouldn't be crying. We've been dating for 16 months and are pretty serious
