I've spent a lot of time just "sitting with" the advice you've all given me about asking about possible other A's. The more I sit with it, the more comfortable I am with letting it go. I think the recent break with SO having dad duty has also helped me detach.
Don't get me wrong. We talk at LEAST once daily and often a lot more. We have a standing lunch date every week. Friday night we have a regular "date" scheduled. We're just not crammed up each other's a$$ all the time. And I think that's a good place for us to be right now.
Okay, off to do my homework. Let's see if I can write something else to pi$$ off my professor! Ahahahahaha! I love being a victim of the Socratic Method! (Not really...)
