My boyfriend and I have been together about 6 months now...I haven't really been able to open up to him and tell him about my past. We broke up about a week ago because of this and we just got back together to see if I could open up more. I'm trying, but it just seems like we have nothing to talk about anymore. I don't know what to say to him. No conversation topics come to my head, and I think he's feeling the same way. What can I do?
