I'd say back off. It's not you that she is thinking about. it is someone who she is not with, "Our dreams will live though we are apart". i don't think it is the guy at work either. There is someone else, maybe not a full relationship, maybe just in her head. But none of this stuff is meant for you. You could ask her why she is playing with the wedding pictures. Perhaps ask her to send the best ones to you. I don't see how the wedding pictures fit with the dreams of another man. You are going to have to let this butterfly go, and if her dreams turn out to be just that -- dreams, then she might come back to you.
