She is making a choice right now, and you must love her enough to honor her choice.
You can not force her to love you,
I would also maybe suggest reading the book the 5 love languages(Dr Gary Chapman) or read about them online. This may show you how you and your wife give and receive love. Unfortunately I think things may be headed in the wrong direction and you can only CONTROL your 50% of the marriage.
