Of course she is putting the blame on you. God forbid she has to take responsibility for anything.
You've heard her out a bunch of times already. She feeds you the same BS, and yet, she changes nothing.
You are young. You share no kids. I believe in the commitment of marriage, but it would best serve you to get out. You have a chance to be with someone who believes in what a M truly is. You have a chance to have a family with someone who shares the same moral values as you.
Stop buying her manipulative BS. She's still acting like a kid and you should me married to a woman.
