What are some things defined/ considered as controlling I should look out for?

[Merandahazuki]

Some of my friends say to watch out for this guy because he is controlling, I was wondering what would be considered controlling that I should look for?

Basically any guy that try’s to change you in my opinion is the definition of controlling. A guy is allowed to introduce you to new ways of thinking, but should also keep an open mind to your feelings and values.

#1: Gets pissed off if you don't text or call him back within a short period of time.
#2: Dictates what you should be doing with your life.
#3: Tries to control who are friends or not.
