Hi, hidden-minded. I think you have to continue to talk to your boyfriend and make sure what you think you see (that he is being cold and distant) is what he is feeling and what he has to say about his actions, whether they are because of something he feels from or about you or from something else.

I would keep reminding myself that whether I feel peace inside of myself is about me and no one else can give me that feeling. If it is from the paranoid disorder I may just have to keep working with myself to remind myself of the good discussions my boyfriend and I have been having and give him and myself time to process each discussion.

You are working on things and that is great but others need time to work on and process their problems and feelings also. So, keep reminding yourself that he is working too (he is discussing things with you, afterall, he hasn't run away) and needs his own space to "work" like you are doing with your things. Nothing can be "solved" all at once or suddenly, it will all take time. Give yourself and him, time.
