my wife has left me for a younger man

After being together for 42 years my wife has deserted me for a younger man.

When I say younger, he is much younger.

I don't see the attraction really.

He is much shorter than me.

He has no more hair than I do.

He is a bit wrinkly and prone to cry at the drop of a hat.

Conversation is not one of his big points.

She says she still loves me and we talk now and then on the phone.

I am lonely and can't live without her.

Any suggestions how I can get her to return to me?
