Importance

I think I place myself at a greater importance to you than you do.  If I don't give you what you need (sexual play), you will seek it elsewhere.  You did so yesterday.  For some reason, I can tell when you do.  I can sense, even over text, that something is off.  That you're distracted and it's not by work.  And so I ask in a roundabout way, and yes, you have been talking to someone else.  I am beginning to feel that if I don't maintain my role, I will be replaced.  What is this relationship?  Is it even dignified enough for that title?
