what is my ex up to here?
	
	
		the other day I was sat behind my ex in lectures, and I noticed that when he logged on to fb my fb chat tab was up - but I Haven't spoken to him on this for about 2 months. there were no other tabs there. therefore he must have had this tab up for a long while during study leave/ had it up the night before lectures and left it there.
I found it a bit wierd- as he broke up with me and goes out of his way to avoid/ ignore me, yet that was there- what's going on?
Its been a year now.
If i ever try and talk to him on chat / or in real life he just goes all awkward and tried to run away asap, short answers, unemotive and cold. But he incessantly watches me from across rooms and I see him looking for me in crowds to orient himself to face me, like he always wants to know where I am :\
please someone help me with this- what's going on in his head... 
thank you x
