Wife very routine in bed

My wife and i have been married for 24 years. She has become very routine in bed and refuses to try and enhance our lovemaking. I have always been turn on when she wears lingerie and heels and put on heavy make-up, but she now refuses or make puts forth little effort and than has an attitude during and after. I just wish that she would want to make me happy and I'm starting to resent the fact that she does not. She is very robotic in bed and refuses to try other things. After 24 years it's become stale. I love her very much but I need help!
