What does he really mean?

Okay so I was seeing this guy for about a month. He persued hot and heavy. Everything was going along fine until an ex hacked into my email and internet accounts. I had to fess up to the new guy about this "other" guy. It seemed to really freak him out. Said he needed to retreat. I was fine with it, although I quite like the new guy. I explained about the other guy to new guy but no dice, still wanted to just be friends. Said he was coming off two brutal past relationships.

Since then I have received an email from him every day. Is he serious about being friends or do we still have a shot?
