Whats it mean when he?

Well it all means that he has control issues...Does he have your myspace pword? If you trusted him enough to give it to him, then don't whine about what he reads there. If he respects you he will not tickle you as you have already informed him that you don't care for it. If you are seated and he is glaring or staring at you, that is a control thing and should be addressed, he knows he is making you uncomfortable and that's why he is doing it, if you are letting him get away with it...you are letting him know that you are weak and he has the upper hand...not a good relationship and certainly one that can become verbally or physically violent...communicate these issues to him and tell him to straighten up or move on.
