Was my friend in prison just using me?

I'm just wondering at what point should I think that I was being used? A guy I went to high school with just got out prison this Friday. He was in there for 10years. We started talked the last 2years of his sentence. We wrote, emailed and he called me everyday. Last time I heard from him was last Tuesday. He wrote me an email saying talk to you soon. I understand he's catching up on lost time with family and friends and life. I'm just wondering if he will ever contact me? I'm alittle worried he just used me while in prison and is gonna just ghost me now.
