Am I in the wrong? men and women please need both sides?

ok I was previously married and I have a child with the guy, after I divorced him I eventually got remarried. I recently had to go to mediation for child custody crap and my ex wanted to keep in touch with me for the childs sake while he was in afgan. he said he had a myspace... I said I do not but anyway I did tell him that I felt uncompfortable doing that so I wanted no comunication with him at all. anyway later that night when I got home I got curiouse and looked up his profile... he did not have one. but anyway my new hubby was looking up some website in the history and saw that I looked him up and he got mad, not he feels weird about everything... then he started looking up signs of a break up and everything. did I do something wrong? its not like I was going to talk to my ex.. I really dont know why I lokked him up someone please help me so that if I am in the wrong I can try to make it right!
