Betty, how old are you?  You need to wake up and smell the coffee.  He is not leaving his wife for you.  End this right now and have more respect for yourself.  He is having the best of both worlds.  He is with you and then he goes HOME to HER.  NOT YOU.  Don't you get it.  Find someone who will love you and nobody else.  Why would you want a guy who tells you he is in love with his wife.  Sorry but that's how I feel.  Good Luck.
