Moving on

I just have a question/need advice.  I was abused for years when I was in my teens and it's now been almost ten years since it stopped but I still seem to be having issues. I feel like most of the time I feel okay and I feel normal. Some days though I can't think about anything else it seems like and sometimes it's hard for me to be intimate with my boyfriend. I'm not sure if other people have similar experiences or if I'm alone in this. I also don't know how much of this to tell my boyfriend because I've told him some but he seems like I should be over it by now. Should I be?
