I urge you to start therapy asap on your own. Hopefully you will be able to get your wife to join you in time. I have been suffering this fate for two decades now. It started after our second child was born. For the first ten years I tried and tried to get my husband to let me know what he was feeling, why he seemed to have no feelings for me anymore. There is no affection, no intimacy, I long just to hear him say my name. He would listen and say he wanted the same things then that would be that and nothing would change. I gave up. Now another ten years has gone by leaving me living a wasted life with nothing to look forward to day after day. There is no emotional support from him and none accepted by him.
Therapy can help especially when facing situations beyond your control. Don't give up but be prepared to make the hard decisions about what you can live with and for how long.
I wish you luck and love.
