<human>: Can you condense the text into three sentences or less?

Hi all,

A month ago I started going out with "Josh". He is a pretty reserved guy but we got to know each other through academia and started to hang out with each other. We had a "DTR" and he said he wanted us to be exclusive and I was really excited.

Since then I have noticed that he will never, and I mean never, initiate contact. Texting, phone calls, email, talking in person he will never start a conversation about anything. If I start a conversation he will answer the questions and return to work. When I asked him about it last week he said that he didn't want to bore me with the details of his life or appear too clingy by blowing me up all day long. I told him there is a happy medium between silence and clinginess and he responded that he was not silent because he always conversed/texted with me whenever I wanted to.

This week I decided to experiment and see how long he take silence from me before contacting. After seven days I started to worry about his safety but I did see him on a campus sidewalk yesterday and he waved at me. 

Am I insane, or do other people have relationships like this? I guess it doesn't bother me so much as long as I know he's alive, but I wonder if other people have similar experiences?
<bot>: Guy asked me out a month ago and never initiates contact with me but will respond to conversation. Is this normal?
