I haven't heard from him in 4 days. If he wants to break-up because it's all too stressful or whatever can't he just say so. I can't move on.

He's now very active on Facebook adding childhood friends but ignores my email of 4 days ago (I wrote a fun and casual email, mirroring his) and one this morning asking him if he was ok and to talk to me whatever the problem is. So far no reaction.

Do you think he's trying the silent treatment because he thinks I won't get it otherwise?
What's wrong with : "I need to concentrate on my health, sorry but I can't have a relationship. It's not helping blahblahblah"? or whatever men can come up with?

I'm 500km from his place!! What is he afraid of?

I really don't get it. I know he's avoiding me because it's just too much but does he want to break-up? :-o I need to know to make decisions about my future etc...
