What made him upset?

Asked by vatofjelly (173) November 23rd, 2015 from iPhone

I met someone a few weeks ago, on a dating app. We went out twice- the second time we went out he asked if I wanted to
come over after we saw a movie. And I said yes, we ended up having sex. The next day I felt terrible, and even
more so because he didn’t even text or call. I forgot that he doesn’t like standing around all
day because he has schizophrenia, and he likes to keep busy to avoid the voices.
And he didn’t bother to call either. I felt a little miffed, and I jumped the gun so I told him
that he didn’t seem interested, and that I was cancelling our date for Sunday. I didn’t mean
to tell him this, and that we could still keep our date. He then said “now you wait
because you cancelled for Sunday” I asked if I should leave him alone for awhile, and
he said “Please” I want to give him his space but at the same time I just want to take back
what I said. What was so wrong in me cancelling even though I explained that I jumped the gun, and didn’t mean to say those things?
