Basically he says I don't always tell him things on purpose.
Last thing was a sexual dream I had (me masturbating in the dream) which I only told him today about. The dream had occurred before last weekend.
These things he talks about that I didn't tell him are all things that I ended up telling him anyway. They weren't things he found out on his own. He got to know because I told him in the end. If I had meant for him to never know, he wouldn't know.
Anyway, he says he can't trust me completely because he thinks I might hide stuff so as not to upset him.
How do I tackle this?
