Someone who checks your diary and throws a tantrum if you won't show 
Avoid like the plague. You are not committed and only just resumed your friendship and already he is behaving like a spoilt 2 year old.
It sounds as if you have gone through this before with someone else, and are drawn to people like this. You know this would be a disaster and your post shows it, but it also shows that nevertheless you are still drawn to him and hope that we will in some way give you 'permission' to keep seeing him.
Sorry, oonana, drop him, drop him, drop himnow and do not even toy with the idea that perhaps this could be made to work. It can't and you know it.
