Thanks for responding and please accept my apologies in the delay in my response.

I had a long overdue positive interaction today. I think we've both realized that if we don't work together on this we're finished. So that's a good start.

I'm going to take your advice about doing something that's not work and then try to have a conversation later. I have noticed that in the past he can totally reject an idea but then accept it a few days later.

I have also had more success previously with presenting a course of action as me attempting to support him or his goals. My ego gets in the way of doing that too often though. It's been tough.

I think I may also have some internal insecurity in regards to him trying to hog the limelight whenever possible. I like to think that I'm above feeling that but I do often have to check myself to make sure I'm doing things for the right reason and not as some kind of passive aggressive retaliation.
