I really don't say that I blame you for going through his posts, since you have reason not to trust him. I think I would do the same thing under the circumstances.

I'm wondering if you need to look hard at this relationship. I don't know that I would want to stay with a guy I couldn't trust to be honest with me. How serious are you two, I'm wondering. Of course, you don't need to respond if you don't want to.
