I am working on a drawing of a sub assembly. I also had a view of the main assembly to show where this sub assembly exists. there is a coworker that is working on a drawing of a different sub assembly within the same main assembly. We are having a referencing issue. When I have my drawing open that includes a view of the main assembly (which includes his sub assembly) he can only open a read only view of his drawing. So my solution was to delete the main assembly view since it is just for reference and then add it back only when I am all done with editing my drawing. When I do this it doesn't seem to get rid of the reference. He still can't open his drawing and when I check the references of my drawing it still shows the main assembly. How can I get rid of this reference if the model had already been deleted from the drawing? Or how do I confirm that all the views of the main model are gone, I cannot find it in the tree anywhere.
Without having the files my best guess is that you have one or more components defined in the context of the main assembly and that is why it shows in the references in your drawing.
To work as a team on the same project you need to look at some system settings to enable collaboration. If you search for "solidworks collaboration settings" on internet you will find some good articles like this one:

In our company we have:
System options->External references->
open documents read only Checked
Load referenced documents None
System options->Collaboration->
Enable multi-user environment Checked
Add shortcut Menu items... Checked
The above settings allow us to work as a team.
On occasion we use the reload tool to get or surrender write access for multiple components in an assembly- make sure to click on the Show references button
