You should not have to change for anyone and if a person can't accept you for who you are then he doesn't deserve you and there are men out there that will appreciate that you are more outgoing and like to talk it seem this guy wants someone he knows he can control easily. Just the fact that you feel you had to change to please him was a warning sign that you would eventually lose yourself in this guy and that is NEVER a good thing. True love is unconditional and without boundaries like, "If you change this I will love you more," or "If you only acted this way I will like you more." or if you looked this way and lost weight I would be more attracted to you." If a person has to put demand on you early in the relationship then it's not going to work because you will find yourself changing everything about you just to please him and then lose yourself in the process. I say you should be glad that you found out what type of person this guy was now. He wants someone he can control and mold into his own kind of woman and that makes them fake and not themselves. Be yourself and find someone who will appreciate you for who you are and not want to change you. You don't have to change anything about yourself the ex is the one that needs to take a look at the way he is or he will find himself alone because being controlling gets kind of old along with fake persona. Find closure with this relationship and I say get back out in the dating scene and make a list of requirements you want in a man and make sure the man has those qualities you are looking for before you even consider dating them this will keep you from finding a man that is so shallow that they look at the outside instead of the inside.
