What would you have done?

So I was dating this guy for about a month, we went out/hung at his place downtown a few times. On our last date, we ended the night with a group of his friends at a bar... and I wake up the next morning on his futon soaked in my own piss. This had never happened to me before so I was not only hungover but confused and flustered. So, I didn't say anything but goodbye and everything, and left. When I got home, I texted him sorry for soiling his futon and to caution him not to sit on it if he hadn't noticed yet. He texts back, "Thank you for having the courage to tell me." At that point I figured, better to just leave this alone for today.

So the next week I texted him about hanging out, and he didn't text back. Alright, if I were him I wouldn't continue a relationship with someone who pissed my futon either... but I found it rude to just not say anything at all. I had the feeling that his last comment to me was out of sarcasm but I can't help but ask why he never said anything past it. Just didn't know what to say, or didn't care anymore? Because he seemed to enjoy our time together until that point, so my thought was that he'd at least be forgiving/understanding. Or just, attempt to communicate in some part.
