I'm thinking of choosing my family over my wife
That must be difficult. Does this mean you're considering divorcing your wife?
Yes she is too demanding.
You should respect both but ty to make it work if you can. You should talk to her and get counseling first before leaving her.
Divorce gives me my freedom. I will make her feel my wrath
If you try to make her feel your wrath then your divorce will become nasty. It's better to end things amicably so that you can move on without any bad feelings. Otherwise your divorce will always be a sore spot and may upset you at times in the future.
