For how long did you date this woman before you married her? I find it very weird that someone would put on such a show and then change completely on the day of the wedding. I also find it very weird that her entire family doesn't speak nicely of her and confirms she put on an act before marriage.
You say you are very much in love with this woman but in truth, it doesn't look like you can stand who she has become, or rather, who she has been all along but managed to hide before she got the ring on her finger.
I honestly don't know what can be done. If she's so calculative that she indeed put on an act to get you to marry her, then there's not much hope to appeal to her senses and to ask her to work (with you) on the marriage. You say you try to talk to her and she reacts with anger, so that's not an option either.
After a year, she most likely isn't going to change again and return to what she was before marriage, especially since her sister confirms that it was all fake. If I were you, I'd probably consider leaving her. I know it's easier said than done, but you clearly aren't happy and hoped to marry a person that was never her, a person that was never real. The only thing (aside from separation) that I can think of is that you give her the cold shoulder a bit. Stop going out of your way to please her if she isn't giving you what you need. That means no massages, no coffees, no compliments. Show her a little what it's like to be treated the way she treats you.1

"I am very much in love with this woman "
no you're not. You're in love with the mask, the performance, the character, the woman who never existed.
