Is this disrespectful?

Im casually dating with no commitment a 33 yr old and im 53. After watching a movie at his place, I noticed he'd finished a 6 pack in under 3 hrs. I was fearful he may mistreatment as other men who drink a lot have. He then tells me he's just going to scroll down his ***..and starts scrolling. I felt that was disrespectful and was tired and wanted to leave anyway. Then he says "oooh hot chicks" which to my perspective as adding insult to injury so I abruptly got up and said we'll there's my exit call. He then accused me of jealousy..I tried telling him I'm not jealous but he wouldn't believe it and so I got annoyed and said we'll it's obvious you're not interested in me so it's time to go. My issue is simply that I felt it disrespectful to tell me he's just going to scroll his *** when I'm there as his guest and the chick's comment was in my view, just disrespectful too. Is this a generation gap thing? Am I missing something here?
