Do you think he likes me?

I have been talking to this guy online for 6 months. Ive known him from hs, but at the time, didnt know him. Well last night we finally spoke on the phone for the first time. It was kind of a thing where online, i was the one that always emailed him first, but when i did, he did cont to talk to me. we were talking about something that was making me axious and then he gave me his number again. So when i called, he ended up talking to me for over an hour. He talked non-stop, it was almost like he did all the talking. Is this a good sign?
