Is he serious!

My son and I have been having some very serious issues. Issues that I never would have expected in my life. It has so thrown me for a loop but I am trying to survive it. He wants nothing to do with me, he is mad about past events in our life, he treats me like crap. Yet, he expects me to do stuff for him and when that doesn't happen he shows up here out of the blue. He says, I have been texting you, and oh yeah the texts were to ask me to do stuff that he is quite capable of doing himself. I say, I know and of course I have been ignoring you. He mumbles something, I don't think he realizes I didn't hear him. He uses my bathroom and as he is leaving without saying another word I say did you have a delivery in the area. He says yeah and that was that. Seriously what was that? Was he checking to see if I was alive?
