Guy gave me his email.. not his number?

So I've been talking to this guy for maybe a week tops online - he deleted his account but sent me a message that if I wanted to continue talking I could email him and he gave me his email.

Why would he remove his account? I guess I'm left wondering, I guess it was nice he gave me his email - but not his number .. you know? Maybe he is not as interested in looking for a relationship?..or there someone else

btw were both 20.. its just I can change that on this account!

Is this weird or what.. I just feel like something is off
