I feel sympathy on you, because I am in a way in a similar situation with you.
Anyway, I do not suggest that you revenge her. Just ler her be. After all, she has been
your wife in the past, and you have slept her.
Just regard your past energy and money
as an enjoy of her body for a certain time.
It is at least much safer than sleepoing a whore.
Now if she wants to live with her own,
or she thinks she can live better with others than you, just let her go.
Let her test. If she indeed get happyness,
it means that you yourself shoud be improved somewhere.
Otherwise, she may miss you in the future,
regret....
Anyhow, she has been proved not a good wife for you, do not reget for letting her go. HOpe you will find a suitable wife of your own.....
Some people laughed at me for letting my wife and even children go with one white guy. I think they are naive. I even help her
in many situation after I realize that she is not a correct wife for me.....
Hope both you and me have good luck in the future.
