Why did he delete whatsapp?

I thought that aguy that I've been speaking to via text for over a month blocked my number. He said he doesn't want a relationship emotinally with me, but he won't see anyone else.
when I asked him if I can date other guys he said "no, do I want to" so I said "no, if I do Ill let you know"
then he said sorry just forget about me. and deleted whatsapp
Was it because of what I said? I really like him. it has been 5 days since this happend. I thought he had blocked me but he uninstalled app. he has not spoken to me since
should I contact him?
