If I am Dave and I am innocent, I will feel the same way that you are annoying. Is there any reason that make you paranoid? If there is, you are justified to chat like that. If there is not, then you are out of line in trying to find a story when there is none.
By the way, I think your relationship does not sound good right now. If you want to keep relationship going, you need to amend your way. Again, you're an annoying woman if Dave is innocent. If Dave is not, then you should be prepared for bad news as it seems that Dave will not tolerate your annoying persistence for long.
