looks like you ex is too hot and your present wife is not!
in that case, you are totally screwed. consider taking your wife to beautician and give her compkete make over. new underwears as well.
drink or smoke and get real horney all the time. dont let love even come. think of your ex (while) and bang your totally make up filled wife. bang bang and more bang

in few months you'll start loving your new wife and forget that ex.
