Odd behavior of a guy or just f boy behavior?

What are the reasons a guy would want to follow / keep up with everything you are doing and always ask about your life but not allow you to follow them back / want you to know what is going on in their life. I get wanting to have your cake and eat it too but does this seem a little far? Or is it all about having control over somebody?
