I don't blog but if I did I wouldn't share it with my partners. I also wouldn't read theirs. I kind of feel that a blog is a safe haven to work through things and express how you feel. If my partner had access I might feel more inhibited which would kind of defeat the purpose of the blog.
I'm actually pretty private about conflicts. I tend to work it out myself then I might talk about it after the fact. I don't like asking for advice or getting unsolicited advice. I'm not someone that needs a lot of support.
