Remember, marital rape is an oxymoron.
As the other anon said, she lost sexual interest in you. Self improve to the point you feel good with yourself. Go to the gym and start lifting.
You can always stay or leave, the choice is yours, but I disagree with the other comment that her lack of sexual arousal is an excuse for you to leave. As long as she is not refusing sex and not cheating, she is not at fault.
